Analyzing the Equation
Sea levels follow a periodic pattern of rise and fall called the tides. The graph below shows the sea level at a certain beach, in feet, over one day, where time t is measured in hours after 12:00 a.m. (midnight) on the first day.
What is the maximum and what does it represent in this context?
The points on the graph are, (5.5,4), (11.5,0), (17.5,4), and (23.5,0).
The maximum is 4 feet and it represents The sea level at high tide.
