In Crescent Moon Bay in July, high tide is at 3:00 pm. The water level is 6 feet at high tide and 2 feet at low tide. Assuming the next high tide is exactly 12 hours later and the height of the water can be modeled by a cosine curve, find an equation for Crescent Moon Bay's water level in July as a function of time (t).

f(t) = 2 cos pi over 6 t + 4

f(t) = 4 cos pi over 6 t + 2

f(t) = 4 cos pi over 2 t + 2

f(t) = 2 cos pi over 2 t + 4
