#### To determine

**To find:** Sketch the graph f-1

#### Answer

Graph is given below:

#### Explanation

The graph for f is in the colour pink while the graph for f-1 is in the colour blue. To draw the graph of f-1, draw the line y=x. Then take the mirror image of f about the line y=x. You will get the graph for f-1. You can observe that graphs for f and f-1 are symmetrical about the line y=x.

**Conclusion:** See the graph.
