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 this set, the input 2 corresponds to two different outputs (4 and 7), which violates the definition of a function.

Decide Whether or Not the Set of Ordered Pairs Defines {(2,4),(2,7),(4,4),(8,−3),(10,5)}\{ ( 2,4 ) , ( 2,7 ) , ( 4,4 ) , ( 8 , - 3 ) , ( 10,5 ) \}{(2,4),(2,7),(4,4),(8,−3),(10,5)}
