Concept explainers
A quarterback tosses a football to a receiver 40 yards downfield. The formula
models the footballs height y, in feet, when it is x yards from the quarterback.
a. How many yards from the quarterback does the football reach its greatest height? What is that height?
b. Ifa defender is 38 yards from the quarterback, how far must he reach to deflect or catch the ball?
c. If the football is neither deflected by the defender nor caught by the receiver, how many yards will it go, to the nearest tenth of a yard, before hitting the ground?
