Chapter 9.5, Problem 49ES

A ball is thrown upward and outward from a height of 6 feet. The height of the ball, y, in feet , can be modeled by
y = − 0.8 x 2 + 3.2 x + 6 ,

Where x is the ball’s horizontal distance, in feet, from where it was thrown.

a. What is the maximum height of the ball and how far from where it was thrown does this occur?
b. How far does the ball travel horizontally before hitting the ground? Round to the nearest tenth of a foot.
c. Graph the equation that models the ball’s parabolic path.
