#### Answer:

Graph a cosine function with an amplitude of

#### Explanation:

Graph

This equation is in the form

Amplitude is the distance on the y-axis between the center line of the graph and the "peak" or "trough".

Period is the distance on the x-axis of one full "cycle" or "repeat" of the graph.

Let's start with

Next, let's graph

Last, let's look at

In other words, one complete "cycle" of cosine is graphed between zero and
