Origin
C16: from Fr. fonction, from L. functio(n-), from fungi 'perform'.
function         
1. <mathematics> (Or "map", "mapping") If D and C are sets (the domain and codomain) then a function f from D to C, normally written "f : D -> C" is a subset of D x C such that: 1. For each d in D there exists some c in C such that (d,c) is an element of f. I.e. the function is defined for every element of D. 2. For each d in D, c1 and c2 in C, if both (d,c1) and (d,c2) are elements of f then c1 = c2. I.e. the function is uniquely defined for every element of D. See also image, inverse, partial function. 2. <programming> Computing usage derives from the mathematical term but is much less strict. In programming (except in functional programming), a function may return different values each time it is called with the same argument values and may have side effects. A procedure is a function which returns no value but has only side-effects. The C language, for example, has no procedures, only functions. ANSI C even defines a type, void, for the result of a function that has no result. (1996-09-01)

Each quantity is said to be a function of the other. Thus, the circumference of a circle is a function of the diameter.
