Answer

$\text{ a function }\\\text{Domain: } \{ -2,0,2,4 \}\\\text{Range: }\{ -3 \}$

Work Step by Step

$\bf{\text{Solution Outline:}}$ To determine if the given table of values is a function, check if all the $x$-values are used only once. The domain is the set of all $x$-values, while the range is the set of all $y$-values. $\bf{\text{Solution Details:}}$ All the $x$-values are used only once in the given table of values. Hence, the given is a function. The domain is the set of all $x$-values, while the range is the set of all $y$-values. Hence, the given table of values has the following characteristics: \begin{array}{l}\require{cancel} \text{ a function }\\\text{Domain: } \{ -2,0,2,4 \}\\\text{Range: }\{ -3 \} .\end{array}
