A short stop makes an error by dropping the ball. As the ball drops, its height (h) in feet, as a function of time (t) is modeled by h (t) = - 16t2 + 3. A slow motion replay of the error shows the play at half speed. What function describes the height of the ball in the replay? (Hint: The function squares the time, so half the time is also squared in the new function.)

A) h (t) = - 16 (0.5t) 2 + 1.5

B) h (t) = (-16t2 + 3) / 2

C) h (t) = - 16 (t/2) 2 + 3

D) h (t) = - 8 (t) 2 + 3
