WebThus, a function is a rule linking one set of values (the domain) to another set of values (the range). A function can link a value from the domain to only one value in the range of the function. If a value in the domain is linked to more than one value in the range, the rule does NOT represent a function; it is just a relation. WebMore formally, a relation is defined as a subset of A × B. The domain of a relation is the set of elements in A that appear in the first coordinates of some ordered pairs, and the image …

Functions may be partial or total. A partial function (or partial mapping) may be undefined for some values of A, and patial functions arise regularly in the computing field.
