Question

Quizplus · Accepted Answer

A relation is a function if each input (x-value) has exactly one output (y-value). In this set, the input -8 is associated with two different outputs (2 and 8), so it does not define a function.

Decide Whether the Relation Defines a Function {(−8,2),(−8,8),(1,7),(3,6),(8,4)}\{ ( - 8,2 ) , ( - 8,8 ) , ( 1,7 ) , ( 3,6 ) , ( 8,4 ) \}{(−8,2),(−8,8),(1,7),(3,6),(8,4)}
