Functions

Algebra

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

Many important relationships can be thought of in terms of functions: In the market for peanuts, the quantity demanded and quantity supplied might each be

3.1 What Are Functions?

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

OverviewMulti-valued functionsDefinitionNotationOther termsSpecifying a functionRepresenting a functionGeneral properties

Several methods for specifying functions of real or complex variables start from a local definition of the function at a point or on a neighbourhood of a point, and then extend by continuity the function to a much larger domain. Frequently, for a starting point there are several possible starting values for the function. For example, in defining the square root as the inverse function of the square function
