Answer
The given relation represents a function.
domain:
$[-2, 2)$
range:
$[0, 3]$
Work Step by Step
Note the all possible vertical lines that will pass through the graph will do so at exactly one point.
The graph passes the vertical line test; therefore, the graph represents a function.
The x-values vary from $-2$ to $2$. However, since a hole (or hollow dot) was used to plot $(2, 1)$, it means that the point is not really part of the graph.
Thus, the domain is $[-2, 2)$.
The y-values vary from $0$ to $3$.
Thus, the range is $[0, 3]$
