Here is a link for function operations at Sparknotes. This site has great summaries, so it's worth bookmarking. There are even practice problems!
Also, I really like how they discuss inverses.

Because of the short day today, we only took benchmarks 9.1 and 10.1. No homework over Thanksgiving, so enjoy yourselves. Come back from the long weekend ready to buckle down and get the last few benchmarks (9 actually) out of the way and our first semester done.
Remember, Grade Report #4 is due Friday, Dec. 2. And that is the FINAL DAY to turn it in. That is also the day of 6 benchmarks and the practice final.

Happy Turkey Day!

I found this great article on imaginary numbers and what they are used for. I hope you find it useful. I just got 3 extra points, too!

Finally back! Here is the problem for this week.
A dog is tied with an 80 foot rope to the corner of a building which measures 60 by 100 feet. Through how many square feet does the rope allow the dog to roam?

After reviewing and collecting HW #25 from Monday, we went to work on the practice test for Ch. 5 part 1. The actual test will be on Thursday. I know we have a rally that day, but if we move it up, we won't be prepared. If we move it to after the 3-day weekend, we won't be prepared.

Test and solutions will be coming up.
