A cliff diver jumps upward from the edge of a clift then begins to descend, so that his path follows a parabola. The diver's height, h(1), above the water in feet is given by
h(t) = -2(1 - 1)2 + 52, where t represents the time in seconds. Graph the function. What is the
vertex and what does it represent in the context of the problem? How many seconds after the
start of the dive does the diver reach the initial height?
