Quizplus · Accepted Answer

A relation is a function if each input (x-value) maps to exactly one output (y-value). Here, the input 3 maps to two different outputs (-1 and 8), so it is not a function.

Determine Whether the Relation Is a Function {(3,−1),(3,8),(5,−6),(7,3),(11,−2)}\{ ( 3 , - 1 ) , ( 3,8 ) , ( 5 , - 6 ) , ( 7,3 ) , ( 11 , - 2 ) \}{(3,−1),(3,8),(5,−6),(7,3),(11,−2)}

Determine Whether the Relation Is a Function $\{ ( 3 , - 1 ) , ( 3,8 ) , ( 5 , - 6 ) , ( 7,3 ) , ( 11 , - 2 ) \}$
