WitrynaA function f: X→ Y f: X → Y from a set X X to a set Y Y is called one-to-one (or injective) if whenever f(x)= f(x′) f ( x) = f ( x ′) for some x,x′ ∈ X x, x ′ ∈ X it necessarily holds that x = x′. x = x ′.

Witrynaone-to-one function or injective function is one of the most common functions used. One-to-One functions define that each element of one set say Set (A) is mapped with a unique element of another set, say, Set (B).
