A sine function has the following key features: Period = 4
Amplitude = 4
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.
