Unit 3 – Functions

In this unit we review the basic concept of a function and emphasize multiple representations of these foundational tools.  Graphical features of functions, including maximums, minimums, intervals of increase and decrease along with domain and range are introduced.  Classic function notation is used throughout the unit.  Average rate of change is introduced as a tool for measuring the growth or decline in a function.  We hope that visitors will use these lessons and give us feedback to make them better.
