2. function


In mathematics, a function f is a non-empty set of ordered pairs (x,f(x)) of which no two can have the same first element. Hence, if f(x) = x2 two ordered pairs are (-2,4) and (2,4). The set of all first elements in a function’s ordered pairs is called the domain; the set of all second elements is the range. In the algebraic expression y = 4x3 + 2, the dependent variable y is a function of the independent variable x, generally written as f(x). Functions are used in all branches of mathematics, physics, and science generally; for example, the formula t = 2pÖ(l/g) shows that for a simple pendulum the time of swing t is a function of its length l and of no other variable quantity (p and g, the acceleration due to gravity, are constants).

3. function


1. The purpose of, or the action carried out by, a program or routine.
2. A general term for a subroutine.
3. In some languages, such as Pascal, a subroutine that returns a value. See also function call, procedure, routine, subroutine.
In computing, a small part of a program that supplies a specific value—for example, the square root of a specified number, or the current date. Most programming languages incorporate a number of built-in functions; some allow programmers to write their own. A function may have one or more arguments (the values on which the function operates). A function key on a keyboard is one that, when pressed, performs a designated task, such as ending a program.
