The domain consists of the first elements of each ordered pair, which are $\{1, -2, -6, 6\}$, and the range consists of the second elements, which are $\{-8, -5, 9\}$.

Give the Domain and Range of the Relation {(1,9),(−2,−8),(−6,−5),(6,−8)}\{ ( 1,9 ) , ( - 2 , - 8 ) , ( - 6 , - 5 ) , ( 6 , - 8 ) \}{(1,9),(−2,−8),(−6,−5),(6,−8)}

Give the Domain and Range of the Relation $\{ ( 1,9 ) , ( - 2 , - 8 ) , ( - 6 , - 5 ) , ( 6 , - 8 ) \}$
