Both onto and one-to-one
WebFunctions can be injections ( one-to-one functions ), surjections ( onto functions) or bijections (both one-to-one and onto ). Informally, an injection has each output mapped to by at most one input, a surjection includes … WebIf f: X → Y is one-one and P and Q are both subsets of X, then f (P ∩ Q) = f (P) ∩ f (Q). If both X and Y are limited with the same number of elements, then f: X → Y is one-one, if and only if f is surjective or onto function. …
