Everything about Codomain

Target set of a mathematical function

In mathematics, a codomain or set of destination of a function is a set into which all of the outputs of the function are constrained to fall. It is the set Y in the notation f : X → Y. The term range is sometimes ambiguously used to refer to either the codomain or the image of a function. Wikipedia →
