A function is one-to-one if each x-value maps to a unique y-value. Here, both (17, -11) and (-16, -11) map to the same y-value (-11), so it is not one-to-one.

Determine Whether the Function Is a One-To-One Function f={(17,−11),(−16,−11),(18,17)}\mathrm { f } = \{ ( 17 , - 11 ) , ( - 16 , - 11 ) , ( 18,17 ) \}f={(17,−11),(−16,−11),(18,17)}
