$(- 1, \frac{1}{9})$ , $(0, 1)$ , $(1, 9)$ , $(2, 81)$

Step 1

Since there is one value of $y$ for every value of $x$ in $(- 1, \frac{1}{9}), (0, 1), (1, 9), (2, 81)$ , this relation is a function.

The relation is a function.

Step 2

Use the definition of the inverse of a function to find the inverse of the set. The inverse is found by swapping the values of $x$ and $y$ in each ordered pair.

$(\frac{1}{9}, - 1), (1, 0), (9, 1), (81, 2)$
