The function p (x) = - 8x2 - 64x can be written in vertex form p (x) = a (x - h) 2 + k, where a =, h =, and k =. To graph the function p, reflect the graph of f (x) = x2 across the x-axis, vertically stretch the graph by a factor of 8, shift the graph units, and then shift the graph units.

A = - 8

h = - 4

k = 128

Shift the graph left 4 units.

Then shift the graph up 128 units.
