In this section of our site you will find worksheets that involve the use of functions.

The following collection of activity sheets will introduce your students to mathematical functions. Functions are at the root of polynomial equations, in that they represent the relationship between inputs (also called "arguments") and outputs, with the understanding that each single input must relate to only one output. Some functions are defined as a formula or algorithm, while others are represented by graphs or tables. However they are represented, every function describes how an input is to be manipulated within or by the function. For example, the function of squaring means that for every input x, the output will be x squared.

Functions are a relationship based system where you have a set of inputs and outputs that are the result of those inputs. Change your inputs and your outputs are affected as well.
