Domain = $\{x\ |\ -3\leq x\leq 5\}$, or $[-3,5]$ Range = $\{-2,1,4\}$
If the function is described by a graph, then the domain is the set of all first coordinates of the points on the graph. The range is the set of all second coordinates. The first coordinates of the points of the graph are between $-3$ and $5$, inclusive. Domain = $\{x\ |\ -3\leq x\leq 5\}$, or $[-3,5]$ The second coordinates are integers, Range = $\{-2,1,4\}$
