I understand the general ideas and concepts from this chapter but there are a couple of problems that I did not find answers to.
1. For homework f2 (its not really about limits, i think, but its in chapter 2 ) I'm not sure how to do #30. I skipped a couple of questions on that homework.
2. On homework E3 I did not really know how to do part B for (27-30). I'm not really sure how I am supposed to explain the behavior of the function to the left and right of each vertical asymptote.
3. On homework f1 #18, I am not sure how the answer is infinity, I didn't get anything near that!
I think that's pretty much it..

For #30 on homework F2, the denominator is equal to (x+2)(x-2). Since the top is a cubic, you have to divide (x-2) into the top of the fraction, x^3-4x^2-11x+30. When you do this, you get x^2-2x-15. then you add the denominator of x+2, and that is your answer since it is now an extended function.
ReplyDeleteI had the same problem with your #2.. :(
and for #18, I got -1, not negative infinity as well... I drew the graph and im not sure how you get negative infinity..
