Quizplus · Accepted Answer

The domain of a relation is the set of all first elements of ordered pairs (x-coordinates), and the range is the set of all second elements (y-coordinates). For the given relation, the domain is $\{-12, -3, -10, 6\}$ and the range is $\{8, -5, 2, -8, 3\}$, which matches choice A after ordering the elements.

Give the Domain and Range of the Relation {(−12,8),(−12,−5),(−3,2),(−10,−8),(6,3)}\{ ( - 12,8 ) , ( - 12 , - 5 ) , ( - 3,2 ) , ( - 10 , - 8 ) , ( 6,3 ) \}{(−12,8),(−12,−5),(−3,2),(−10,−8),(6,3)}

Give the Domain and Range of the Relation $\{ ( - 12,8 ) , ( - 12 , - 5 ) , ( - 3,2 ) , ( - 10 , - 8 ) , ( 6,3 ) \}$
