Question

Quizplus · Accepted Answer

For a set of ordered pairs to define a function, each input (x-value) must correspond to exactly one output (y-value). In the given set, the input 1 corresponds to two different outputs (3 and -5), which violates the definition of a function.

Decide Whether or Not the Set of Ordered Pairs Defines {(−3,8),(−2,−3),(1,3),(1,−5)}\{ ( - 3,8 ) , ( - 2 , - 3 ) , ( 1,3 ) , ( 1 , - 5 ) \}{(−3,8),(−2,−3),(1,3),(1,−5)}
