David Longshot is known for his long golf drives. Today he hit the ball yards and estimated that the ball reached a maximum height of yards. Find a quadratic equation that would model the path of the golf ball.

A sketch of the graph would look like the one below.

First quadrant, x axis scaled in 50's, from 0 to 300, Curve, opening down, rises through the origin, to the point (125, comma 15), then falls & passes through the point (250, comma 0).

You must find the value of a for the quadratic equation.

What is the vertex?
Use the vertex and another point to solve for .
