Question

VERY IMPORTANT TEST AND I NEED CORRECT ANSWER!!

Answer 1

Given equation y=a(x-h)^2 +k.

Solution:

Subtracting k from both sides, we get

y-k=a(x-h)^2 +k-k

y-k =a(x-h)^2

Dividing both sides by (x-h)^2, we get

(y-k)/(x-h)^2 =a(x-h)^2/(x-h)^2

$\frac{(y-k)}{(x-h)^2} =a$

Therefore, correct option is D option

D). a= (y-k)/(x-h)^2
