A rocket is shot into the air at a velocity of 48 ft/ sec. The equation is h(t) = -16t^2+48t+4
1) How far off the ground did the rocket start from?
2) Using the quadratic function, how high the rocket will be at its maximum point?
3) How long will it take the rocket to reach that maximum point?
4) Rewrite the function into vertex form.
5) Predict when the rocket will reach the ground.
6) Sketch the function. ( Label at least 5 points.)
