Amplitude is half the vertical distance from the highest point to the lowest, so half of 6 = 3.

Period is the horizontal length of one complete cycle, so π

One equation, noting that the graph goes through (0, 0) and sin 0 = 0,

is y = -3 sin (2x)

-3 because the graph goes down instead of up after (0,0) and 2 because the number in front of x = the frequency (number of full cycles) from 0 to 2π
