A function is one-to-one if each input maps to a unique output. In this case, each input (-3, -4, -18) maps to a unique output (17, -5, 19), so the function is one-to-one.

Determine Whether the Function Is a One-To-One Function f={(−3,17),(−4,−5),(−18,19)}\mathrm { f } = \{ ( - 3,17 ) , ( - 4 , - 5 ) , ( - 18,19 ) \}f={(−3,17),(−4,−5),(−18,19)}

Determine Whether the Function Is a One-To-One Function $\mathrm { f } = \{ ( - 3,17 ) , ( - 4 , - 5 ) , ( - 18,19 ) \}$
