#### Answer

The relation $\{(0,-2),(2,-1),(2,-4),(5,3) \}$ $does \text{ } not$ define a function. The set $\{0,2,5\}$ is its $\underline{\text{
domain
}},$ and the set $\{-2,-1,-4,3\}$ is its $\underline{\text{
range
}}.$

#### Work Step by Step

The given relation is not a function because the first component, $2,$ is not unique.
The set of first components is the domain.
The set of second components is the range.
