IPA: //bɪˈdʒɛktɪv//
KK: /bɪˈdʒɛk.tɪv/
A type of function in mathematics where each input is paired with exactly one unique output, and each output is paired with exactly one unique input.
In mathematics, a bijective function ensures that every element of the domain corresponds to a unique element in the codomain.
Bijective → It is formed from "bi-" (meaning two) and "ject" (from Latin "jacere", meaning to throw). The word describes a function that pairs each element of one set with exactly one element of another set, thus establishing a two-way relationship.
Think of 'two' ('bi-') things being 'thrown' together ('ject') in a way that each one matches perfectly with another.
