Determine the amplitude, period, and phase shift of the function. Graph the function. y=4 cos (2mx-4)

A swimmer on a floating air mattress will follow the rise and fall of the waves in lake. When the person is on the top of the wave her feet are 0.5m above the average surface height of the lake. When she is in a trough her feet dig 0.5m into the water (-0.5m). The peaks of the waves are separated by two seconds. Create an equation of the sinusoidal function that models this movement assuming that she starts at the average surface height of the lake and heads upwards.

The graph of the cosine function has been vertically compressed by a factor of 3, reflected in the y-axis, has a period of 720°, has been shifted left 60°, and has been shifted up 5. Write the equation of this function.
