A road is made in such a way that the center of the road is higher off the ground than the sides of the road, in order to allow
Jet001 [13]

Remark.

The problem is a bit indistinct. Where exactly are the two edges of the road? I'm going to say that they are the x intercepts, but that may not be true. Certainly it does not have to be true at all.


Graph.

A graph has been made for you. The maximum is marked for you. It is an approximation The actual height can be more accurately found.


Height

y = (-1/200)(x - 16)(x + 16)

y = (-1/200)*(x^2 - 256)


The maximum height for this graph only is when x = 0.Other graphs require completing the square.


y = (-1/200) * (-256)

y = 1.28 exactly. I thought the graph might be rounding the answer. It is not.
