Question

Quizplus · Accepted Answer

A relation is a function if each input (first component of each ordered pair) maps to exactly one output (second component). Here, the input 2 maps to two different outputs (-7 and -2), so it is not a function.

Determine Whether the Relation Is Also a Function {(2,−7),(2,−2),(6,7),(7,4),(10,−6)}\{ ( 2 , - 7 ) , ( 2 , - 2 ) , ( 6,7 ) , ( 7,4 ) , ( 10 , - 6 ) \}{(2,−7),(2,−2),(6,7),(7,4),(10,−6)}
