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).
