Quizplus · Accepted Answer

A relation is a function if each input (x-value) has exactly one output (y-value). In this set, the input -9 is associated with two different outputs (9 and -1), so it is not a function.

Determine Whether the Relation Is a Function {(−9,9),(−9,−1),(2,−8),(5,4),(10,−9)}\{ ( - 9,9 ) , ( - 9 , - 1 ) , ( 2 , - 8 ) , ( 5,4 ) , ( 10 , - 9 ) \}{(−9,9),(−9,−1),(2,−8),(5,4),(10,−9)}

Determine Whether the Relation Is a Function $\{ ( - 9,9 ) , ( - 9 , - 1 ) , ( 2 , - 8 ) , ( 5,4 ) , ( 10 , - 9 ) \}$
