Cosine is an **even** function so the

The amplitude of this function is 2.

This is a graph of the cos(x) shifted 3 units vertically.

The **red** curve is the **original** equation.

The **blue** curve is the **new** equation showing that cosine is an **even function** .

The **red** and **blue** color signify the same functions as above.

The point of this image is to show that both functions result in the same curve.
