Your homework for tonight involves work with sign diagrams and rational functions.
Read through Example 9 on sign diagrams on page 68, and see if you can answer the assigned parts of question 2 and 3 (see below) without graphing the given function.
Also read through the textbook section on rational functions (2F), paying particular attention to the discussion of asymptotes. Note that the textbook’s definition of a rational function is actually more limited that the (correct) definition we’ve used, which is how they avoid talking about polynomials in this section.
Complete all of the section 2E questions listed below, and as many of the questions below from 2F as you are able.
Exercise 2E questions 1fhk, 2adg, 3agh
Exercise 2F questions 1bc, 2ab
