Answer: x^2 - 14x + 49

Explanation:

1) Divide the coefficient of x by 2:

14 / 2 = 7

2) so you have to add 7^2 = 49

x^2 - 14x + 49

3) that trinomial is equivalent to:

=> (x - 7)^2

4) prove that using the formula (a - b)^2 = a^2 - 2ab + b^2

(x - 7)^2 = x^2 - 14x + 49

Then you have to add 49 to complete the square. and form a perfect square trinomial.

Answer:

B. $H(x)=-.008(x-82)^{2}+83$

Step-by-step explanation:

Well lets graph the following equation first,

H(x) = -.011(x - 82)^2 + 75

Then lets graph all the other equations.

Look at the image below↓

So A.

The purple line does not go farther or higher,

so A. is incorrect

The black line goes higher and farther,

meaning it is correct.

The red line goes farther but not higher.

So it is incorrect

Again the blue line does not go farther of higher.

So its wrong.

Thus,

answer choice B. $H(x)=-.008(x-82)^{2}+83$ is correct.

Hope this helps :)
