For the first thirty minutes of class from 11:33-11:53. Next we took out our laptops and checked out rational functions. Homework will be due next Thursday November 5th, which is when we take the Unit Test.
Today we explored rational function: graphically, numerically, algebraically
We graphed two rational functions on Grapher. Which caused a frenzy in the class. We checked for domain, zeros, shape, asymptotes and other fun graphing things. After analyzing the functions we learned that one day we are expected to do this by hand... Oh no! The two programs we used today were Numbers and Grapher. We graphically analyzed first then we numerically analyzed.
Numerically: Find zeros: Find where numerator= 0. Find vertical asymptotes: Find where denominator= 0. To find the end behavior: Divide top and bottom by the largest power of x and let x--->infinity. After learning these steps we put them into practice and tried them out on some problems.
Homework ?’s that we didn't get to---43, 47
Homework for next class: p. 193/7, 11, 13, 15, 23, 37, 47, 57, 71 [Use your calculator and/or Grapher to explore- your goal should be to do each without technology on the quiz.]
If you forgot your permission slip, bring it in.
You can pass in your IOU’s at the beginning of next week.

Thanks, Kayla. Don't forget to label your post.
ReplyDeleteI was planning on looking at 43 next class, but I hadn't written down that anyone needed to see 47- thanks!
