On a certain day in February, the first high tide occurs at 3 AM, when the wa- ter rises 6.1 meters higher than aver- age. The first low tide occurs at 9 AM. At that time, the water is 1.7 meters lower than average. On this particular day, the tides were at their midline exactly at midnight, t = 0. The tides on this day can be modeled by a periodic function. Create a model that represents the height of the tide on this day. (0,2.2) [3,6.1) (15.6.1) (9,-1.7) 10 The graph models the tides of the ocean on a certain day in February.
