The domain of a relation consists of all the first elements in each ordered pair, and the range consists of all the second elements. For the given relation, the domain is $\{-7, -2, 9, 15\}$ and the range is $\{-7, -2, 0, 4\}$.

Find the Domain and the Range of the Relation {(9,4),(−7,0),(−2,−2),(15,−7)}\{ ( 9,4 ) , ( - 7,0 ) , ( - 2 , - 2 ) , ( 15 , - 7 ) \}{(9,4),(−7,0),(−2,−2),(15,−7)}

Find the Domain and the Range of the Relation $\{ ( 9,4 ) , ( - 7,0 ) , ( - 2 , - 2 ) , ( 15 , - 7 ) \}$
