"Domain={-3,-1,0,1,2}, &, Range="{-2,0,3,4}.

Explanation:

When a Relation or Function , say, f, is defined as a Set of

Ordered Pairs, i.e., f={(x,y)}., its Domain and Range ,

denoted by D and R resp., are the Sets , defined by,

D={ x : (x,y) in f}, and, R={y : (x,y) in f}.

Clearly, in our case,

D={-3,-1,0,1,2}, &, R={-2,0,3,4}.
