Any function can be decomposed into a surjection and an injection. By collapsing all arguments mapping to a given fixed image, every surjection induces a bijection defined on a quotient of its domain. A is called domain of f and b is called codomain of f. In casual terms, it means that every vector in \w\ can be the output of \t\. If the codomain of a function is also its range, then the function is onto or surjective. If a function does not map two different elements in the domain to the same element in the range, it is onetoone or injective.
