20 points-

a sine function has the following key features:

period = 4

amplitude = 3

midline: y=−1

y-intercept: (0, -1)

the function is not a reflection of its parent function over the x-axis.

use the sine tool to graph the function. the first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
