For the function f(x) = -2sin(3x), determine its amplitude and period, and then graph it for two periods. Enter the exact answers. For the number π, either choose π from the bar at the top or type in Pi (with a capital P). Amplitude: A = Period: P = Using your answers for the amplitude and period, select the correct graph of the function f(x) = -2sin(3x).

Determine the amplitude and period of the function rt=0.5cos(t-π/2)+3 without graphing the function first. Sketch a graph of the function after determining its period and amplitude, then label the period and amplitude. All inputs are in radians.
