## 1.1 Functions and Their Graphs

A good deal of our work with exploring the concept of a limit will be to look at the graphs of functions. This section will review some of the ideas around how functions and their graphs look, and we will look at two new concepts in functions: step functions and piecewise functions.

Things you should know after today:

- definition of odd and even functions
- what a "one to one" function is
- what the greatest integer function is, and why is it a step function
- how to graph a piecewise function
