Find the Inverse (9,-6) , (8,-5) , (7,3) , (4,3)

Since there is one value of ${\displaystyle y}$ for every value of ${\displaystyle x}$ in ${\displaystyle (9,-6),(8,-5),(7,3),(4,3)}$, this relation is a function.

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 ${\displaystyle x}$ and ${\displaystyle y}$ in each ordered pair.
