At an ocean depth of 20 meters, a buoy bobs up and then down 2 meters from the ocean's depth. Four seconds pass from the time the buoy is at its highest point to when it is at its lowest point. Assume at x = 0, the buoy is at normal ocean depth.

Question

The first point must be on the mid-line and the second point must be a maximum or minimum value on the graph closest to the first point.
