    en.wikipedia.org/wiki/Function_(mathematics)

    In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. [1] The set X is called the domain of the function [2] and the set Y is called the codomain of the function. [3] Functions were originally the idealization of how a varying quantity depends on another quantity.

    What is a Function? A function relates an input to an output. It is like a machine that has an input and an output. And the output is related somehow to the input. " f (x) = ... " is the classic way of writing a function. And there are other ways, as you will see!

  4. Function | Definition, Types, Examples, & Facts | Britannica

    www.britannica.com/science/function-mathematics

    Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences.

  5. What is a Function in Maths? A function in maths is a special relationship among the inputs (i.e. the domain) and their outputs (known as the codomain) where each input has exactly one output, and the output can be traced back to its input. An example of a simple function is f (x) = x 2.

    A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions. **Unit guides are here!**

  7. What Are Functions in Mathematics? A function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Let A & B be any two non-empty sets; mapping from A to B will be a function only when every element in set A has one end and only one image in set B. Example:

    Function in Math is a special type of relation in which every output has a unique input. Learn more about function, its types, domain and range, representation, graph and example in this article.

  9. Function -- from Wolfram MathWorld

    mathworld.wolfram.com/Function.html

    A function is a relation that uniquely associates members of one set with members of another set. More formally, a function from to is an object such that every is uniquely associated with an object . A function is therefore a many-to-one (or sometimes one-to-one) relation.

  10. Section 3.4 : The Definition of a Function - Pauls Online Math...

    tutorial.math.lamar.edu/Classes/Alg/FunctionDefn.aspx

    In this section we will formally define relations and functions. We also give a “working definition” of a function to help understand just what a function is. We introduce function notation and work several examples illustrating how it works. We also define the domain and range of a function.

  11. 3.1 What Are Functions? - MIT Mathematics

    math.mit.edu/~djk/calculus_beginners/chapter03/section01.html

    The simplest definition is: a function is a bunch of ordered pairs of things (in our case the things will be numbers, but they can be otherwise), with the property that the first members of the pairs are all different from one another.
