To find the domain, we look at the first coordinate of each ordered pair, which gives us $\{ 0, 5, 7, 9, 10 \}$. To find the range, we look at the second coordinate of each ordered pair, which gives us $\{ -7, 9, 12 \}$. So the correct choice is $\boxed{	extbf{(C)}}$.

Find the Domain and the Range of the Relation {(0,0),(7,−7),(5,12),(9,9),(10,9)}\{ ( 0,0 ) , ( 7 , - 7 ) , ( 5,12 ) , ( 9,9 ) , ( 10,9 ) \}{(0,0),(7,−7),(5,12),(9,9),(10,9)}
