Please help- Xavier went cliff diving in Acapulco while vacationing with some friends. His height as a function of time could be modeled by the function h(t) = - 16t² + 64t + 80, where t is the time in seconds and h is the height in feet. Be sure to show all of your work and calculations.
A. What was the height of the cliff Xavier jumped off? How can you tell from looking at the equation?
B. How long did it take for Xavier to reach his maximum height? Explain.
C. what was the highest point that Xavier reached?
D. Xavier hit the water after how many seconds?
E. Graph the function in demos, is there any data represented by the equation that does not make sense? explain.
