Outrageously Funny Word Dictionary :: Bijections

👉 A bijective function, also called a one-to-one correspondence or injection, is a mapping between two sets such that each element of the first set has exactly one corresponding element in the second set. This means that no two elements have more than one image. In other words, if you have a bijection from A to B, then for every element x in A there exists an unique y in B such that f(x) = y. The inverse of a bijection is also a bijection
