The height of a fish t seconds after it is thrown to a dolphin from a 64-foot-tall platform can be modeled by the equation h(t) = — 1612 + 48t + 64, where ht) is the height of the fish in feet. The graph of the function is shown.
a. Estimate the t-coordinate at which the height of the fish changes from increasing to decreasing. Describe the meaning in terms of the context of the situation.

b. Describe and interpret the end behavior of ht) in the context of the situation.
