In mathematics, and more specifically in naive set theory, 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.iven a function f: X â Y, the set X is the domain of f; the set Y is the codomain of f. In the expression f (x), x is the argument and f (x) is the value. One can think of an argument as an input to the function, and the value as the output.
