alg II rational function review guide

We will have our rational function test next Friday 3/23/17 as it seems not to conflict with other classes.  The test will consist of (number of problems is stated after concept):

adding or subtracting rational expressions - 1
dividing rational functions - 1
solving a rational function and determining reasonableness of solutions - 3 to 4
inverse or direct variation - 1

Sorry for this late addtion, but as I said in class, there will be 1 graphing question and 1 on domain and range.  But to my credit, I already put graphing problems to practice on p 370 below so if you were practicing, then you are going to be ready anyway!


There will also be a performance task on Wednesday 3/21/17 that will definitely have at least 2 d = rt and probably a very complex fraction on it.  May see popcorn prism or penguin problem again. (efficiency)


Here are some problems that I found in our book that would be good to do/ redo:

p. 363 #11-14, 17, 27
p. 370 # 11-13 (be prepared to have the equation given in word form or go from graph to equation!)
p. 380 #21-22, 31-33
p. 388 #21-23, 40-43, 45
p.  396 #3, 20-28 evens, 34
p. 401 #17
p. 402 #26-27

Most of the d=rt problems are not in the book, so see if you can access the ones we did in previous classes.

If you need videos to help you, go to YouTube and search rational functions and maybe use "Khan Academy" or "Thinkwellvids Burger" to use ones that I would recommend.
