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 set of points has the following characteristics: \begin{array}{l}\require{cancel} \text{ a function }\\\text{Domain: all real numbers} \\\text{Range: all real numbers} .\end{array}
