Function (mathematics) - Wikipedia
WEBIn mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

WEBIf a function is defined by an equation, then the domain of the function is the set of “permissible x-values,” the values that produce a real number response defined by the equation. We sometimes like to say that the domain of a function is the set of “OK x-values to use in the equation.”
