Question

Quizplus · Accepted Answer

The domain and range of a relation are the sets of all first and second elements of the ordered pairs, respectively. In this relation, both the domain and range include the same numbers $\{ - 7 , - 2,3,4 \}$, making option D correct.

Give the Domain and Range of the Relation {(3,3),(−2,−2),(−7,−7),(4,4)}\{ ( 3,3 ) , ( - 2 , - 2 ) , ( - 7 , - 7 ) , ( 4,4 ) \}{(3,3),(−2,−2),(−7,−7),(4,4)}

Give the Domain and Range of the Relation $\{ ( 3,3 ) , ( - 2 , - 2 ) , ( - 7 , - 7 ) , ( 4,4 ) \}$
