Question
The height y (in feet) of a punted football is approximated by
y = − (16/2025) x2 +(9/5)x+(3/2)
where x is the horizontal distance (in feet) from the point at which the ball is punted. (See figure.)
(a) Use a graphing utility to graph the path of the football.
(b) How high is the ball when it is punted? (Hint: Find y when x = 0.)
_____________ ft
