jason jumped off of a cliff into the ocean in Acapuluco while vacationing with some friends. h(t)=-16t^2+16t+480

Question

how long did it take for Jason to reach his maximum height ?

what was the highest point that Jason reached? 

Jason hit the water after how many seconds ?

Answer 1

Put this function in vertex form.

 

h(t) = -16(t² - t + (1/4)) + 4 + 480

 

h(t) = -16(t - (1/2))² + 484

 

 

Now you can get the maximum height and time of maximum height from this form.
