John and Phil were playing tennis. They each hit a tennis ball at the same time and measured the how high the tennis balls went and how long it took for each one to land on the tennis court. The graph represents the height of the tennis ball t seconds after it was hit by John. The function f given by f(t)=(−16t−2)(t−2) represents the height of the tennis ball t seconds after it was hit by Phil. In both functions, height is measured in feet. Part 1. Whose tennis ball hit the tennis court first? When did that happen? Part 2. Phil's tennis ball reached its maximum height after 15/16 seconds. Did Phil's tennis ball reach a higher maximum than John's tennis ball?
