Answer

$\text{Domain: } \{-4,-1,2,5\} \\\text{Range: } \{-2,0,2\} \\\text{The set defines a function}$

Work Step by Step

The domain of a set of ordered pairs is the set of all the $x-$coordinates of the ordered pairs, while the range is the set of all $y-$coordinates. Hence, the given set , $\{ (-4,-2),(-1,0), (2,0), (5,2) \}$ has the following characteristics: \begin{array}{l}\require{cancel} \text{Domain: } \{-4,-1,2,5\} \\\text{Range: } \{-2,0,2\} \\\text{The set defines a function} .\end{array} The set defines a function since the $x-$coordinates of the ordered pairs are unique (do not repeat).
