Quizplus · Accepted Answer

In a function, each input (x-value) can only have one output (y-value). However, in this relation, the input -8 is associated with two different outputs (3 and -9). Therefore, it is not a function. This relation is not a function because it has multiple outputs (y-values) for the same input (x-value) (-8).
