Question

Which function in vertex form is equivalent to f(x) = x2 + 8 – 16x?

Answer 1

f(x)= (x+8)^2 + 200

Explanation:

-b/2a gives you the x coordinate of the vertex and then plug it in for x to get the y coordinate. Put it in the formula (f()x= (x-h)^2 +k).

H is the x coordinate and K is the y coordinate

Answer 2

A)f(x) = (x – 8)2 – 56
