Question

Quizplus · Accepted Answer

In a function, each input (or x-value) must correspond to exactly one output (or y-value). Here, the input -8 corresponds to two different outputs (-9 and -3), so it is not a function.

Determine Whether the Relation Is Also a Function {(−8,−9),(−8,−3),(−1,−3),(6,−8),(9,−5)}\{ ( - 8 , - 9 ) , ( - 8 , - 3 ) , ( - 1 , - 3 ) , ( 6 , - 8 ) , ( 9 , - 5 ) \}{(−8,−9),(−8,−3),(−1,−3),(6,−8),(9,−5)}

Determine Whether the Relation Is Also a Function $\{ ( - 8 , - 9 ) , ( - 8 , - 3 ) , ( - 1 , - 3 ) , ( 6 , - 8 ) , ( 9 , - 5 ) \}$
