Each input (first number in each pair) maps to exactly one output (second number in each pair), which defines a function.

Decide Whether the Relation Defines a Function {(1,−4),(2,−2),(6,7),(8,−7),(11,−1)}\{ ( 1 , - 4 ) , ( 2 , - 2 ) , ( 6,7 ) , ( 8 , - 7 ) , ( 11 , - 1 ) \}{(1,−4),(2,−2),(6,7),(8,−7),(11,−1)}

Decide Whether the Relation Defines a Function $\{ ( 1 , - 4 ) , ( 2 , - 2 ) , ( 6,7 ) , ( 8 , - 7 ) , ( 11 , - 1 ) \}$
