Find the Inverse {(-2,4),(2,-4),(8,-2),(-8,2)}

Since there is one value of ${\displaystyle y}$ for every value of ${\displaystyle x}$ in ${\displaystyle (-2,4),(2,-4),(8,-2),(-8,2)}$, 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.
