Describing Inverses of Functions

To find the inverse of a relation written as coordinate pairs, we exchange the $x\text{-}$ and $y\text{-}$coordinates of each ordered pair.

Let's write the inverse relation as a data set. $$\begin{array}{c}\{(9,\text{-}3),(\text{-}1,4),(9,\text{-}11),(0,7)\}\end{array}$$
