A function is one-to-one if each input maps to a unique output. In this function, all inputs (6, -4, -6, -8) have different outputs (-1, 0, 1, 2), so it is one-to-one.

Determine Whether the Function Is a One-To-One Function f={(6,−1),(−4,0),(−6,1),(−8,2)}\mathrm { f } = \{ ( 6 , - 1 ) , ( - 4,0 ) , ( - 6,1 ) , ( - 8,2 ) \}f={(6,−1),(−4,0),(−6,1),(−8,2)}
