The domain of a relation consists of all the first elements of the ordered pairs, and the range consists of all the second elements. For the given relation, the domain is $\{-5, -2, 12\}$ and the range is $\{-5, -6, 7, -8\}$.

Give the Domain and Range of the Relation {(−5,−5),(−2,−6),(12,7),(12,−8)}\{ ( - 5 , - 5 ) , ( - 2 , - 6 ) , ( 12,7 ) , ( 12 , - 8 ) \}{(−5,−5),(−2,−6),(12,7),(12,−8)}

Give the Domain and Range of the Relation $\{ ( - 5 , - 5 ) , ( - 2 , - 6 ) , ( 12,7 ) , ( 12 , - 8 ) \}$
