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 -7 maps to two different outputs (-6 and 7), so it is not a function.

Determine Whether the Relation Is Also a Function {(−7,−6),(−7,7),(2,−9),(5,4),(8,9)}\{ ( - 7 , - 6 ) , ( - 7,7 ) , ( 2 , - 9 ) , ( 5,4 ) , ( 8,9 ) \}{(−7,−6),(−7,7),(2,−9),(5,4),(8,9)}
