The curve represents a function of $x$. Domain: $[-3, 2]$ Range: $[-2, 2]$
RECALL: The Vertical Line test states that if all vertical lines will pass through a graph in at most one point, then the graph represents a function of $x$. Note that all vertical lines will pass through the given graph in at most one point only. Thus, the given graph represents a function of $x$. The domain is the set of $x$ values covered by the graph, while the range is the set of $y$ values covered by the graph of the function. The graph covers the x-values from $-3$ to $2$. Thus, the domain is $[-3, 2]$. The graph covers the y-values from $-2$ to $2$, Thus, the range is $[-2, 2]$.
