Equation: f(x)=x−0.05x2
, where x is the horizontal distance traveled and f(x) is the height above the ground. all units are in meters.

a) either graph this quadratic by hand or by using some graphing utility and printing a copy.
b) from what height was the projectile launched?
c) how far did the projectile travel from the point of launch?
d) what was the maximum height of the projectile?
e) what would be some physical similarities and differences if the leading coefficient in the quadratic model were -0.025 instead of -0.05?
