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.

Explanation:

The most simple sine function, considered the parent function, is:

That function has:

The more general sine function is:

That function has:

Now, you have to draw the sine function with the given key features:

Substitute the know values and use the y-intercept to find C:

Substitute (0, -1)

Hence, the function to graph is:

To draw that function use this:

With that you can understand the graphs attached.
