Throughout the day, the depth of water at the end of a dock varies with the tides. The function h (t) = 5 cosine (0.5 t minus 2) + 7 represents the height, in feet, of the water t hours after midnight.
Which graph shows the height of the water at the dock at any time after midnight?
On a coordinate plane, feet is on the x-axis and depth is on the y-axis. A curve starts at (0, 5). It decreases through the y-axis. It has a minimum of y = 2 and a maximum of y =12. It goes through 1 cycle in 13 feet.
