Answer
$\text{domain: }
\{x|x=-2\}
\\\text{range: all real numbers}
\\\text{not a function}
$
Work Step by Step
Using the Vertical Line Test, a vertical line drawn at $x=-2$ will hit the given graph in more than 1 point. Hence, the given graph is not a function.
The $x-$value of the given graph is always $-2$, while the $y-$ values can be anything. Hence, the graph has the following characteristics:
\begin{array}{l}
\text{domain: }
\{x|x=-2\}
\\\text{range: all real numbers}
\\\text{not a function}
.\end{array}
