The domain of a relation is the set of all first elements of the ordered pairs, and the range is the set of all second elements. For the given relation, the domain is $\{-2, 2, 12\}$ and the range is $\{-10, 9, 12\}$.

Find the Domain and the Range of the Relation {(12,12),(−2,−10),(2,9)}\{ ( 12,12 ) , ( - 2 , - 10 ) , ( 2,9 ) \}{(12,12),(−2,−10),(2,9)}

Find the Domain and the Range of the Relation $\{ ( 12,12 ) , ( - 2 , - 10 ) , ( 2,9 ) \}$
