We will be studying how complex numbers relate to polynomial functions. The new edition of the book covers all of this material in one section. It used to take two, with more homework problems. Given that I liked the old coverage of the material better, you will be given copies of all the homework problems (and the answers to the odds) from the old edition. We will be spending several days on the topic and will then have a quiz. The quiz will be skill based and could happen at any time after the first three days of basic instruction so stay on top of your homework.

Big Giant Review Problem Answer Key
You can download the answer key to the BIG problem given out on Friday.
Please note that there were two typos in that problem and I have fixed them in the answer key (so your answers may vary from mine - want to try parts of the problem again without the typos for extra practice?). The first typo was a problem for most of the questions since it is in the function definition. The part of the function used for negative values of x should have simplified to -x^2. The other typo was in question one and should say even instead of odd.
I apologize for the graphs being so small. The only way to make piecewise functions is on my calculator - a very small screen.
