Functions can even be used to make intricate designs and works of art! An example of this is fractal art, which is created by repeating simple functions many times. 

. By plotting these in a coordinate system you can visualize the relationship between the input, 

, of the function. This is what we mean by drawing a graph.

A function is a relationship between two — or more — variables. If you input a number into a function, it can only output one value.

The horizontal axis in a coordinate system

The vertical axis in a coordinate system. Often called 

Every point in the coordinate system has coordinates of the form 

. The first coordinate tells you where the point is along the 

-axis, and the second coordinate tells you where the point is placed along the 

A tool for representing points using a pair of numerical values as coordinates. Consists of two axes, 

-axis and four sections called a quadrants.
