Function Graph

Explore FunctionGraph on MathWorld

A function graph is a set of points showing the values taken by a function. This type of plot is called simply a "graph" in common parlance, but is distinct from a collection of points and lines (also called a network) that mathematicians refer to when they speak of a "graph."

Function graph is an elementary-school-level concept. It is listed in the California State Standards for Grade 5.


Function: A function is a relation that uniquely associates members of one set with members of another set. The term "function" is sometimes implicitly understood to mean continuous function, linear function, or function into the complex numbers.
