Quizplus · Accepted Answer

A function is one-to-one if each input maps to a unique output. In this function, all inputs (-7, 8, 1, -1) map to unique outputs (-8, 7, 1, -1), so it is one-to-one.

Determine Whether the Function Is a One-To-One Function f={(−7,−8),(8,7),(1,1),(−1,−1)}\mathrm { f } = \{ ( - 7 , - 8 ) , ( 8,7 ) , ( 1,1 ) , ( - 1 , - 1 ) \}f={(−7,−8),(8,7),(1,1),(−1,−1)}

Determine Whether the Function Is a One-To-One Function $\mathrm { f } = \{ ( - 7 , - 8 ) , ( 8,7 ) , ( 1,1 ) , ( - 1 , - 1 ) \}$
