a diver stands on a platform 15 ft above a lake. he doesn't dive off the platform and lands in the water below. His height (h) above the lake after X seconds is shown on the graph below. what is the maximum height the diver reached?

We are asked about the maximum height of the diver given the graph. we notice from the graph that the maximum point is h = 20 feet, therefore, the maximum height is 20 feet.
