Function operations are a must know for algebra students.  Let’s review what the word “operation” means.  In math an  operation is what you can do to numbers- i.e. add, subtract, multiply or divide.  However operations not only apply to numbers but to a whole range of things to include functions.  So as you will see below you can add, subtract, multiply and divide functions.  Also there are some special function operations called composite functions and inverse functions.  Don’t have too much fun!  enjoy!


some key topics that involve function operations:

* independent and dependent variables
* range and domain
* composite functions
* function inverse
