Answer

$\text{domain: all real numbers} \\\text{range: } \{y|y\ge0\} \\\text{a function} $

Work Step by Step

Using the Vertical Line Test, a vertical line drawn anywhere will hit the given graph at only 1 point. Hence, the given graph is a function. The $x-$values of the given graph can be any number, while the $y-$ values are always non-negative. Hence, the graph has the following characteristics: \begin{array}{l} \text{domain: all real numbers} \\\text{range: } \{y|y\ge0\} \\\text{a function} .\end{array}
