Two-dimensional graph

From Wikipedia, the free encyclopedia

A two-dimensional graph is the graph of a function of one variable f(x). Provided that x and f(x) are real numbers, the graph can be represented as a straight or curved curve in a two-dimensional Cartesian coordinate system.

[edit] Example

The graph of the cubic polynomial on the real line

is

{(x, x³-9x) : x is a real number}.

If this set is plotted on a Cartesian plane, the result is a curve (see figure).
