Please type the explanation in comment box thanks please give a small graph if possible

For the function f (x) = -2 sin (x - determine its amplitude and period, and then graph it for two periods. Enter the exact answers. For the number 7 , either choose 7 from the bar at the top or type in Pi (with a capital P). Amplitude: A = Number Period: P = Using your answers for the amplitude and period, select the correct graph of the function f (x) = -2 sin (x
