Abottle rocket is launched upward at 128 feet per second from a platform that is 136 feet high. its path can be mapped by the equation h = -16t^2 + v'o't + h'o (where h=height, t=time, v'o=initial velocity, and h'o=initial height).

which of the following equations represents the height of the rocket in vertex form?

a. h=-16(t-8)^2+136
b. h=-16(t^2-8t)+136
c. h=16(t-4)^2
d. h=-16(t-4)^2+392
