Work for Friday 12/23

In class we worked on a problem sheet "Exponent practice (continued)". If
you've finished that sheet, there's no homework over the vacation.
If you have some problems left over, do those before our next class on
Wednesday 1/4/06.

Hope you all enjoy the holidays and vacation. See you in January!

We will have a test Monday on quadratic functions (most of Chapter 5, with
some extensions and deletions as detailed on the review sheet from today's
