Topics:
Here are some videos from PartickJMT which show how to use test points:
Example 1 (polynomial inequality)
Example 2 (polynomial inequality)
Example 1 (rational inequality)
Example 2 (rational inequality)
Example 3 (rational inequality)
Here is a video which shows how to use the graphs: you can also look at the textbook’s examples, which use the graphs as well. (Examples 12.4)
Solving a rational inequality using its graph (Sorry, this is from YouTube so another video may autoplay afterward: I don’t know how to stop this.)
Homework:
• Review the examples discussed in class. You may also want to view the videos I have linked above.
• Do the following exercises from the textbook (there is no WeBWorK for this): Exercises 13.1(a-f) and 13.2(a-e)
