How do you find the discontinuity point of a function?
discontinuity point of a function is a point at which the function is not continuous. There are three types of discontinuities: removable, jump, and essential.
A removable discontinuity is a point at which the function is not defined, but the limit of the function as x approaches the discontinuity point from both sides is equal to a finite value.
A jump discontinuity is a point at which the function is defined, but the limit of the function as x approaches the discontinuity point from both sides is not equal.
An essential discontinuity is a point at which the function is not defined and the limit of the function as x approaches the discontinuity point from both sides is infinite or does not exist.
To find the discontinuity points of a function, you can:
Plot the function on a graph and look for any breaks or gaps in the graph.
Use the algebraic definition of continuity to determine whether the function is continuous at a given point.
Use the limit definition of continuity to determine whether the function is continuous at a given point.
Use a computer algebra system (CAS) to find the discontinuity points of a function.

When a prism and a pyramid have the same height and the same base the volume of the prism is greater than the pyramid?
Yes, the given statement is true the volume of the prism is greater than the volume of the pyramid when they have same base and same height.
As given in the question,
Formula required to calculate the volume of the pyramid and volume of the prism is given by :
Volume of a pyramid = (1/3) × (base area )× ( height )
Volume of a prism = (Base area) × (height)
When the base and height of the pyramid is same as that of the base and height of the prism then
Volume of the pyramid = ( 1/3) × ( Base area × height )
⇒Volume of the pyramid = ( 1/3) × ( Volume of the prism )
⇒Volume of the prism = 3 × ( Volume of the pyramid )
⇒Volume of the prism > Volume of the pyramid
Therefore, the volume of the prism is greater than the volume of pyramid is a true statement.

What is the relationship between a function and its
inverse?
A function is a group of components or inputs that have a relationship and produce an outcome. A function's inverse is the function's opposite. When a function's inverse is applied, its domain changes to its range, and conversely.
What is a function?The core of calculus in math is the concept of functions. The unique types of connections are the ones with functions. Mathematical functions are represented as a rule that, for each input x, produces a distinct result.
As per the question, the relationship between a function and its inverse will be:
1. A group of elements or inputs that are related to one another and produce an output is referred to as a function.
2. A function's reverse is called a function's inverse.

What is the y-intercept of 2x y =- 3?
The y-intercept of the equation 2x - y = -3 is 3 and in ordered pair form is (0,3).
What is the y-intercept of the given equation?The slope-intercept formula is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the equation in the question
2x - y = -3
First, we solve form for y and reorder in slope intercept form.
2x - y = -3
Subtract 2x from both sides
2x - 2x- y = -3 - 2x
- y = -3 - 2x
Divide each term by -1
y = 3 + 2x
Reorder in slope intercept form
y = 2x + 3
To find the y-intercept, replace x with zero and solve for y
y = 2(0) + 3
y = 3
Therefore, the y-intercept is 3.

37. Rajiv gets pocket money from his farther everyday. Out of pocket money, he saves ₹ 2.75 on 1st day and on each
succeeding day he increases his saving by 25 paise
(i) On which day he saves 7.75?
(ii) Find the difference between the amount saved by Rajiv on 25th day and 14th day.
(iii) Find the sum of amount saved on first 10 days.
Step-by-step explanation:
first we come up with a formulae:
Amount of money saved = 2.25+0.25x,
where x is the number of days
Answer:
1. 7.75 = 2.25 + 0.25(x)
7.75 - 2.25/ 0.25 = x
x = 20
2. 2.25+0.25(25) - 2.25 +0.25(14)
= 9.75
3. 2.25 + 0.25(10)
= 4.75
I hope i explained it well...
( i ) 21st day he saves 7.75
(ii) the difference between the amount saved by Rajiv on the 25th day and the 14th day is 2.75 rupees.
(iii) the sum of the amount saved in the first 10 days is 5 rupees.
Solution: (i) given: on each succeeding day he increases his saving by 25 paise.
2.75 rupees he saves on the first day
so = 2.75 +(0.25×20)
= 2.75+5
= 7.75 rupees
(ii) amount saved by Rajiv on the 25th day is:
= 2.75+(0.25×24)
= 2.75 + 6
= 8.75
amount saved by Rajiv on the 14th day is :
=2.75+(0.25×13)
=2.75+3.25
=6
therefore the difference between Rajiv' saving on the 25th day and the 14th day is : = 8.75-6
= 2.75
(iii) the sum of the amount saved in the first 10 days is :
= 2.75+(0.25 ×9)
= 2.75+2.25

Write the equation of the line in fully simplified slope-intercept form.
The required equation of the line is y = 3x + 2 in slope-intercept form.
To write the equation of a line in slope-intercept form, we need to know the slope of the line and the y-intercept. The slope of a line is defined as the change in y divided by the change in x for two points on the line.
According to the given graph, the required solution would be as:
For the given points (2, 2) and (4, 8),
So, the slope is : m = 8 - 2 / 4 - 2 = 6 / 2 = 3.
With the slope and y-intercept, we can write the equation of the line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
For the point (2, 2), the y-coordinate is the y-intercept, so the y-intercept is 2.
So, the equation is y = 3x + 2
Therefore, the required equation of the line is y = 3x + 2 in slope-intercept form.

What is the multiplicity of 0?
The multiplicity of 0 is the number of times that 0 appears as a root of a polynomial equation.
In other words, it is the number of times that 0 is a solution to the equation. For example, the equation x^2 - 4x + 4 has two solutions, 0 and 4. The multiplicity of 0 is therefore 2, since 0 is a repeated solution.
If a polynomial equation has only one 0 as a solution, the multiplicity of 0 is 1. In some cases, a polynomial equation may have no 0s as a solution, in which case the multiplicity of 0 is 0.
In general, the multiplicity of a number is the number of times it appears as a solution to a polynomial equation. For example, the equation x^2 - 2x + 8 has two solutions, 2 and 4. The multiplicity of 2 is 1, since 2 appears only once as a solution, while the multiplicity of 4 is 2, since 4 appears twice as a solution.

How will you know if a function increases and decreases?
A function increases if the output value of function increases on increasing the input value and the function decreses if the output value of function decreases on increasing the input value
As we know a function is nothing but a relation between input values and output values where each input has exactly one output.
Consider a function y = f(x)
For a given function if the value of y increases on increasing the value of x, then the function is an increasing function
If the y-value decreases on increasing the value of x, then the function is a decreasing function.
Another method is that if we need to determine whether a function f(x) is increasing or decreasing at point 'a'.
If a function is differentiable on an open interval, we calculate the derivative of function f(x)
If the derivative f′(x) > 0 on an open interval, then function f(x) is increasing on that interval.
If the derivative f′(x) < 0 on an open interval, then function f(x) is decreasing on that interval.
Therefore, if the output value of function increases on increasing the input value then the function is an increasing function and if the output value of function decreases on increasing the input value then the function is an decreasing function.

What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
x² + kx - 5/4 = 0 be equation (1)

How do you translate coordinates?
To translate an entire triangle, find the coordinates of each of the triangle's vertices, add the horizontal translation then plot the three translated points.
Whenever an object is moved from one location to the next without changing its size, shape, or orientation, a translation takes place. If we know which way and how far the figure to be moved, we can draw the translation in the coordinate plane.
Use P′(x+a,y+b) to translate the point P(x,y), a unit to the right, and b unit up. Use P′(x−a,y−b) to translate the point P(x,y), a unit to the left and b unit to the lower.
There are some steps of translating the triangle:
Step 1: Find the coordinates of each of the triangle's vertices in step one.
Step 2: Add the horizontal translation value to each vertex's x-coordinate and the vertical translation value to each point's y-coordinate to translate each point. If the horizontal translation is to the left or the vertical translation is downward for these translations, add a negative number.
Step 3: Plot the three translated points and draw the triangle by drawing a straight line between each pair of points.
