Quizplus · Accepted Answer

A relation is a function if each input (x-value) maps to exactly one output (y-value). Here, the input 4 maps to two different outputs (-3 and -4), so it is not a function.

Decide Whether the Relation Is a Function {(−5,−2),(−3,−9),(4,−3),(4,−4)}\{ ( - 5 , - 2 ) , ( - 3 , - 9 ) , ( 4 , - 3 ) , ( 4 , - 4 ) \}{(−5,−2),(−3,−9),(4,−3),(4,−4)}
