A relation is a function if each input (x-value) maps to exactly one output (y-value). Here, the input 1 maps to two different outputs (1 and 7), so it is not a function.

Decide Whether the Relation Is a Function {(−6,4),(−1,5),(1,1),(1,7)}\{ ( - 6,4 ) , ( - 1,5 ) , ( 1,1 ) , ( 1,7 ) \}{(−6,4),(−1,5),(1,1),(1,7)}
