$(1, 2)$ , $(9, 0)$

Step 1

Since there is one value of $y$ for every value of $x$ in $(1, 2), (9, 0)$ , 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.

$(2, 1), (0, 9)$
