Answer:
f(x) = 3(x - 2)² + 4
OR
f(x) = 3x² - 12x + 16
Step-by-step explanation:
Vertex form of a parabola:
y = a(x - h)² + kStandard form of a parabola:
y = ax² + bx + cLet's find the vertex of this parabola.
(h, k) → (2, 4)In order to find the a-value (vertex form), let's use another point besides the vertex on the parabola.
Using (3, 7) for (x, y), let's substitute this point and the vertex (2, 4) for (h, k) into the vertex form equation and solve for a.
7 = a[(3) - (2)]² + 4Simplify using PEMDAS.
7 = a(1)² + 47 = a + 4Subtract 4 from both sides.
a = 3Now we have (h, k) and a of the vertex form.
y = a(x - h)² + k → y = 3(x - 2)² + 4In order to convert from vertex to standard form, simplify the equation by FOILing.
y = 3(x - 2)² + 4y = 3(x² - 4x + 4) + 4Distribute 3 inside the parentheses.
y = 3x² - 12x + 12 + 4Combine like terms.
y = 3x² - 12x + 16Therefore, we have the answer:
Vertex form:
f(x) = 3(x - 2)² + 4Standard form:
f(x) = 3x² - 12x + 16Related Questions

What is the Mark the absolute minimum point of the graph
Answers
Answer:
is in the point x = 1, y = -5
Step-by-step explanation:
The absolute minimum of a graph is the point that is the most far below the x-axis.
Such that if we draw a horizontal line parallel to this point, this line should not intersect the graph in another point. It is usually associated with the lowest value of the variable y.
In the graph, we can see that in the extremes we have dots, so the graph does not continue.
Then we can be sure that the absolute minimum is at the bottom of the large curve, that is in the point x = 1, y = -5

Rearrange x = 3g + 2 to make g the subject g=?
Answers
Step-by-step explanation:
x=3g+2
you need to move the equation to the other side, first you'd start with the one furtherest from g, which is is 2.
x = 3g
-2. - 2
and minus it from both sides
x-2=3g
3g is like 3x, which is 3 times x and you need to use the opposite operators so times would become divide.
so now it becomes x-2 over 3=g

find the measurement indicated in each parallelogram first one says 60 and second says 79 please help !
Answers
Answer:
1. 60+X=180(adjacent angles of parallelogram)
X=120
2. X=79(opposite angles of parallelogram)
Angles P and R are congruent so
P & R both have a value of 60°
60x2= 120°
360-120=240° are left
Angles S and Q are also congruent so divide 240 by two
240/2=120°
Answer 1.)Q=120°
Again it equals 360° total
Angles X and V are congruent so
X & V both have a value of 79°
Answer 2.) V=79°

A student observes a difference in the activity level of fish at a pet store. The fish in an aquarium near the window are swimming around more quickly tha the fish in an aquarium placed in the back of the store. The student forms a hypothesis about the effect of sunlight on fish activity levels and arranges to conduct an experiment. Which variable could be an independent variable in the student's experiment? types of fish sold speed of swimming fish amount of time fish were active temperature of water in fish tank
Answers
Answer: Types of fish sold
The type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).
What are Variables?
A variable is any kind of characteristic, number, or quantity which can be measured or counted. It can also be called a data item. Examples of variables are age, sex, occupation income and expenses, country of birth, capital expenditure, class grade, eye color, and vehicle type.
There are two types of Variables are:
1. Dependent variable
A dependent variable is a type of variable which changes as the result of independent variable manipulation which is the outcome interested in measuring, and it "depends on" the independent variable.
2. Independent variable
An independent variable is the type of variable which is manipulated or varied in an experimental study in order to detect its effects. This is "independent" because it is not affected by any other variable in the study.
In above case, this is independent because types of fish characteristic is not dependent for the experiment.
Thus, the type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).

What is the general equation of a Straight line?The general equation of a straight line is -y = mx + c
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis
Other possible equations of line are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a line through (9, 4) and (0, 5).
The slope of the line will be -
[m] = (4 - 5)/(9 - 0)
[m] = - 1/9
Therefore, the slope of the line will be m = -1/9.
