A function is one-to-one if each x-value maps to a unique y-value. Here, both (-8, -6) and (-18, -6) map to the same y-value (-6), so it is not one-to-one.

Determine Whether the Function Is a One-To-One Function f={(−8,−6),(−18,−6),(−5,8)}f = \{ ( - 8 , - 6 ) , ( - 18 , - 6 ) , ( - 5,8 ) \}f={(−8,−6),(−18,−6),(−5,8)}

Determine Whether the Function Is a One-To-One Function $f = \{ ( - 8 , - 6 ) , ( - 18 , - 6 ) , ( - 5,8 ) \}$
