#### Answer

Not a function
The domain is $\left\{-2, -1, 0, 1, 2\right\}$.
The range is $\left\{-2, -1, 1, 3\right\}$.

#### Work Step by Step

The x-value $-1$ is paired with two different y-values.
This means that the relation is NOT a function.
The x-values are -2, -1, 0, 1, 2 so the domain is $\left\{-2, -1, 0, 1, 2\right\}$.
The y-values are -2, -1, 1, 3 so the range is $\left\{-2, -1, 1, 3\right\}$.
