Answer
Domain = $\{-3,-2,-1,0,1,2,3\}$
Range = $\{-2,-1,1,2 \}$
Work Step by Step
The graph contains the points
$(-3,-2),\ (-2,-2),\ (-1,-1),\ (0,-1),\ (1,1),\ (2,1),\ (3,2)$
When a function is given as a set of ordered pairs,
the domain is the set of all first coordinates
and the range is the set of all second coordinates.
A graph is a collection of ordered pairs (x,f(x)), plotted on a coordinate system.
Domain = $\{-3,-2,-1,0,1,2,3\}$
Range = $\{-2,-1,1,2 \}$
