determine the amplitude, period, and phase shift for y=7cos(0-90°) and use them to plot the graph of the function.

amplitude = 7; period = 360°; phase shift = 90°

amplitude = 7; period = 180°; phase shift = 90°

amplitude = 1; period = 360°; phase shift = 90°

amplitude = 7; period = 90°; phase shift = 360°
