The domain of a set of ordered pairs is the set of all first elements, and the range is the set of all second elements. For the given set, the domain is $\{5, 5, 6, 3, -9\}$, which simplifies to $\{6, -9, 3, 5\}$ when duplicates are removed and the numbers are listed in no particular order. The range is $\{1, -4, 7, 4, -6\}$, which simplifies to $\{7, -6, 4, -4, 1\}$ when listed without duplicates.

Find the Domain and Range {(5,1),(5,−4),(6,7),(3,4),(−9,−6)}\{ ( 5,1 ) , ( 5 , - 4 ) , ( 6,7 ) , ( 3,4 ) , ( - 9 , - 6 ) \}{(5,1),(5,−4),(6,7),(3,4),(−9,−6)}
