Quizplus · Accepted Answer

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 $\{ -6, -3, 1, 6 \}$ and the range is $\{ -9, -4, 8 \}$.

Give the Domain and Range of the Relation {(1,8),(−3,−9),(−6,−4),(6,−9)}\{ ( 1,8 ) , ( - 3 , - 9 ) , ( - 6 , - 4 ) , ( 6 , - 9 ) \}{(1,8),(−3,−9),(−6,−4),(6,−9)}

Give the Domain and Range of the Relation $\{ ( 1,8 ) , ( - 3 , - 9 ) , ( - 6 , - 4 ) , ( 6 , - 9 ) \}$
