To determine

**To sketch:** The graph of

Expert Solution

Identify the points from the given graph.

The points plotted in the graph are (0, 1), (2, 0) and (4, −1).

Interchange the *x* and *y* values to find the points of inverse graph.

Thus, the inverse function has, (1, 0), (0, 2) and (−1, 4).

Also notice that the domain of the graph

Thus, the domain of the graph

So, to sketch the graph of
*y* = *x* and plot the points (1, 0), (0, 2) and (−1, 4).

Thus, the graph of

From Figure 1, notice that the graph of
*f* about *y* = *x*. Also, notice that the graph *f* follows the cosine curve.
