A ball is thrown straight up. We know its height H in feet after t seconds is given by the function H(t) = 128t - 16t squared.

I am required to find H(2), H(6), H(3), H(5). Can someone help me with setting up the function?

From the looks of it you just plug in the numbers. So you have the function H(t) = 128t - 16t^2 so lets do the first one lets find H(2). Notice that the 2 represents time (t) so you just plug in 2 everywhere you see a t in your equation. So H(2) = 128(2) - 16(2)^2 and just solve the equation. You do the same with the other ones: H(6), H(3), H(5)
