### Notes:

- Show enough work on all problems to convince me you know what you're doing. If your
work consists of using a graphing utility, then show the graph.
- Numbers 1, 4, 5, 6, and 7 should be worked by hand, not using the graphing utility, although a
graphing utility can be used to check the results.
- All problems are directly from the textbook, but they may be odd or even.
