Invertiivisyys
Invertiivisyys, often translated as invertibility or bijectivity in English, refers to a fundamental property in mathematics concerning functions and mappings. A function is considered invertible if it has a unique inverse function. This means that for every element in the codomain of the function, there is exactly one element in the domain that maps to it. Essentially, an invertible function allows you to unambiguously reverse the mapping.
For a function f from set A to set B to be invertible, it must satisfy two
The inverse function, denoted as f⁻¹, takes an element from the codomain of f and maps it
