Question

abb0t · Answer

You could take the derivative of the function, set it equal to zero and solve for "t".

abb0t · Answer

Plug in that value into ur initial function to find the max height.

So the ball would take  0.9375 seconds to reach its maximum height.And the maximum height would be is 20.0625.The range would be 6 is less then or equal to h is less than or equal to 20.0625.Correct?
