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.

Find the Domain and Range {(8.66,15.86),(8.666,−15.9),(97,0),(1.29,−8)}\left\{ ( 8.66,15.86 ) , ( 8.666 , - 15.9 ) , \left( \frac { 9 } { 7 } , 0 \right) , ( 1.29 , - 8 ) \right\}{(8.66,15.86),(8.666,−15.9),(79​,0),(1.29,−8)}
