In which form is the following function written? y+20=8(x+7)^2

Wewaii [24]

Answer:

(a variation of) vertex form

Step-by-step explanation:

For vertical scale factor "a" and vertex (h, k), the vertex form of the equation for a parabola can be written as ...

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

If k is subtracted from this equation, an alternate form is ...

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

This latter version of vertex form is the form your equation has, where ...

a = 8
(h, k) = (-7, -20)
