    There are no theorems in this section.

  3. Properties/Tricks/Hints/Etc.

    There are some handy rules of thumb for power functions, tex2html_wrap_inline135 :

    Some properties of trigonometric functions are also discussed:

  4. Summary

    This chapter provides a summary of the variety of functions we encounter most often in this class, and shows how they can be used to model real world situations. The shapes of the graphs of these functions are seen repeatedly in a variety of data sets: hence, appreciation of and familiarity with the graphs of these functions can be important, as graphs of data can suggest mathematical models to us.

    Several examples are given which demonstrate the importance of linear functions in the modeling process. Linear models may be derived in different ways, such as

Problems we might do together:
