Coy · Answer 1

A. - 16x²+64x+8

B. 72 ft.

Step-by-step explanation: A. Expand the perfect square binomial - 16 (x²-4x+4) + 72, dist. - 16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)

B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.
