Section 5: Functions: Defining, Evaluating and Graphing

Graphing Functions

The plot command introduced in Section 3 works the same for functions.

Example 1

For example, consider the function $f\left(x\right)=\cos x$  on $\left[-\pi ,\pi \right]$ .

To plot several functions simultaneously, use the same syntax as introduced in Section 3. For example, let us plot the functions $f\left(x\right)$ , $f\left(2x\right)$ , and $2f\left(x\right)$  on the same graph.

Try this!

For the function f defined above, plot the functions $f\left(x\right)$, $f\left(x\right)+2$, and $f\left(x+2\right)$ on the same graph.
