A relation is a function if each input (x-value) maps to exactly one output (y-value). Here, the input -9 maps to two different outputs (5 and -4), so it is not a function.

Determine Whether the Relation Is a Function {(−9,5),(−9,−4),(1,−6),(5,−5),(8,−2)}\{ ( - 9,5 ) , ( - 9 , - 4 ) , ( 1 , - 6 ) , ( 5 , - 5 ) , ( 8 , - 2 ) \}{(−9,5),(−9,−4),(1,−6),(5,−5),(8,−2)}

Determine Whether the Relation Is a Function $\{ ( - 9,5 ) , ( - 9 , - 4 ) , ( 1 , - 6 ) , ( 5 , - 5 ) , ( 8 , - 2 ) \}$
