Answer
$\text{Domain: }
(-\infty, 0]\cup[2,\infty)
\\\text{Range: any real number}
$
Work Step by Step
The $x-$values of the given graph can be any number except the numbers between $0$ to $2$. The $y-$values can be any number. Hence, the given graph has the following characteristics:
\begin{array}{l}\require{cancel}
\text{Domain: }
(-\infty, 0]\cup[2,\infty)
\\\text{Range: any real number}
.\end{array}
