We started class with a warm-up of using different technology (calculator, Grapher, Wolframalpha, etc) and our intelligence to get as much possible information on the given rational function for a graph. We should be working our way to graphing these functions with only a pencil and ourselves!
Then we went over homework problems from last class: #43 and #47 (page 179).
After that, we got our quizzes back and went over them.
We then talked about the warm-up. The equation was x4-2x3-2x2-2x-3 / x3+6x2+11x-6.
We factored it into (x+1)(x-3)(x2+1) / (x-3)(x-2)(x-1), then divided it to find a slant asymptote of x+4. From there we continued to graph the function fully. Cool!
In the last couple of minutes we briefly went over graphing inequalities of rational functions (on tonight’s homework).
