A baseball is thrown directly upward into the air from an elevated platform. The two equations below model the height H(t) in feet of the ball after t
seconds of being thrown.

How long does it take for the baseball to reach its maximum height? (2)
b. What was the initial height of the ball? (2)

form A : h(t)= -16t^2 + 96t +7
form b: -16(t-3)^2 +151

help please
