The correct statement of function is the function is continuous.
What is Function?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
As, functions approach the same value as x approaches 0.
Now, -x² +4x +1 at x= 2 we get
= -4 + 8 +1 = 5
and, 1/2x + 3 = 1+3= 4
So, we reject the statement.
Now, as x increases without bound,
1/2x +3 increases with bound.
Therefore the statement B is true statement.

Answer:
The mapping can also be represented as the set of ordered pairs: (4, 9) (5, 10) (6, 11) (7, 12). The ordered pair preserves the directional property of the relation. It is consistent with the order of points plotted on a Cartesian Plane represented by (",$). In the Arrow Diagram that follows.

Evaluate the expression below when n = 4. If needed, answer as a fraction or a decimal.
6(n+8) - 5n
When n is equal to 4, the expression 6(n+8) - 5n evaluates to 52. This means that if we replace the variable n with 4, the expression simplifies to the constant value of 52.
To evaluate the expression 6(n+8) - 5n when n = 4, we substitute n with 4 and simplify step by step:
First, we substitute n with 4 in the expression:
6(4+8) - 5(4)
Next, we simplify the parentheses:
6(12) - 5(4)
Multiplying within the parentheses:
72 - 20
Finally, we subtract the two values:
52
As a result, the formula 6(n+8) - 5n evaluates to 52 when n is equal to 4. This indicates that the expression becomes simpler if we substitute the variable n with the number 4, which is 52.

At a middle school, 18% of all seventh grades are teacher's aides. 64 seventh graders are teacher's aides, how many seventh graders are at the middle school? (Round to the nearest whole)
Answer:
356 Seventh Graders
Step-by-step explanation:
All I did was find out what number 64 was 18% of, and that gave me the answer. I took 64 and put it over 18%, and set it across from X over 100%. I did the cross multiplication, and got 355.56, but rounded it to get 356. So there are 356 total seventh graders. Hope this is helpful...have a great day! :))

Determine whether the equation is an identity or not an identity. Sin theta/cos theta + cos theta/sin theta = cos theta sin theta
Answer:
The equation is not an identity.
Step-by-step explanation:
Since we have Sin theta/cos theta + cos theta/sin theta = cos theta sin theta, we re-write as Sinθ/cosθ + cosθ/sinθ = cosθsinθ where theta = θ.
For the equation to be an identity, we need to show that L.H.S(left-hand-side)= R.H.S (right-hand-side)
So,
Sinθ/cosθ + cosθ/sinθ = (Sin²θ + cos²θ)/cosθsinθ (taking L.C.M = cosθsinθ)
= 1/cosθsinθ (Sin²θ + cos²θ = 1)
≠ cosθsinθ
Since L.H.S = Sinθ/cosθ + cosθ/sinθ = 1/cosθsinθ ≠ R.H.S = cosθsinθ, the equation is not an identity.
