$f = ((1, 0), (3, 4), (5, 2), (8, 9))$

Step 1

Since there is one value of $y$ for every value of $x$ in $(1, 0), (3, 4), (5, 2), (8, 9)$ , 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.

$(0, 1), (4, 3), (2, 5), (9, 8)$
