Which set of ordered pairs does not represent a function? { ( 5 , − 1 ) , ( − 6 , − 7 ) , ( − 5 , − 7 ) , ( 9 , 6 ) } {(5,−1),(−6,−7),(−5,−7),(9,6)} { ( 8 , − 1 ) , ( − 4 , − 1 ) , ( − 6 , 5 ) , ( 4 , − 2 ) } {(8,−1),(−4,−1),(−6,5),(4,−2)} { ( 8 , 6 ) , ( − 1 , 2 ) , ( 8 , − 8 ) , ( 1 , 9 ) } {(8,6),(−1,2),(8,−8),(1,9)} { ( − 1 , 1 ) , ( 7 , − 2 ) , ( − 7 , − 3 ) , ( 0 , − 3 ) } {(−1,1),(7,−2),(−7,−3),(0,−3)} Submit Answer

Respuesta :

Answer:  { ( 8 , 6 ) , ( − 1 , 2 ) , ( 8 , − 8 ) , ( 1 , 9 ) }

Explanation:

The x coordinate 8 repeats itself for the points (8,6) and (8,-8). This is enough info to see that we don't have a function. A function is only possible when any x value goes to exactly one y value.
