# Mathematics - Domain of a function (set of input )

In mathematics, the domain of definition or simply the domain of a function is the set of “input” or argument values for which the function is defined. That is, the function provides an “output” or value for each member of the domain.

In the notation: $$f(A) = B \\ f : A \rightarrow B$$

• X is the domain
• and Y is the codomain.
