A football player punts a ball. The path of the ball can be modeled by the equation y = –0.004x2 + x + 2.5, where x is the horizontal distance, in feet, the ball travels and y is the height, in feet, of the ball. How far from the football player will the ball land? Round to the nearest tenth of a foot.

0=–0.004x2 + x + 2.5
x=-2.475
x=252.5
distance cant be negative, so the 2nd must be the logical answer.
as it happens this is D.
