Math Domain Codomain

In mathematics the codomain or set of destination of a function is the set into which all of the output of the function is constrained to fall.

Math domain codomain. The set of actual output values is called. The codomain is the set of values that could possibly come out. While this is similar to range vs domain in the sense that domain deals with input values and the x in f x codomain deals with potential f x outputs.

Domain codomain and range of a function concept examples with step by step explanation. It only takes a minute to sign up. The codomain is actually part of the definition of the function.

The definition of the codomain is often especially difficult to understand. Apart from the stuff given in this section if you need any other stuff in math please use our google custom search here.

Illustrated definition of codomain. For example the function has a domain that consists of the set of all real numbers and a range of all real numbers greater than or equal to zero. A codomain is part of a function f if f is defined as a triple x y g where x is called the domain of f.

As usual the best way to understand what the domain and codomain are is. The codomain and range are both on the output side but are subtly different. X y the term range is sometimes ambiguously used to refer to either the codomain or image of a function.
