What's the question?

OpenStudy (anonymous):

I would guess the limit as t approaches 0????

1) At exactly 6:00 pm a football is kicked upward from ground level with an initial velocity of 32 feet per second. The function h(t) = -16t^2 + 32t gives the height of the ball in feet after t seconds a) What is the maximum height reached by the football? b) After how many seconds does the ball touch the ground? c) At exactly what time does the ball touch the ground?

OpenStudy (anonymous):

To find when the ball touches the ground make h(t) = 0 and solve

OpenStudy (anonymous):

then add that to 6:00

max height you need to determine the axis of symetry (x) and wht the corresponding y value is
