On Dolphin Beach, the high tide is 2.2 meters and only occurs at 12 a.m. and 12 p.m. The low tide is 1 meter and only occurs at 6 a.m. and 6 p.m. Which function models the height of the tide t hours after 12 a.m.?

Assuming that t = 0   = 12 AM....the correct function is

 

h(t) = 0.6cos ( pi * t /6 ) + 1.6
