Topics:
• Difference quotients: more practice (Exercise 3.4(a) and (f))
• Functions defined by a graph: reading off function values, find domain and range. (Examples 3.7 and 3.8, on handout)
• Introduction to graphing calculator (to be continued next time)
Homework:
• Review and study the examples we discussed in class (listed above). Make sure that you understand how we can find the domain and range of a function from its graph.
• Do the WeBWorK: please do not wait to the last minute!
• Also do the following from the textbook: Exercises 3.7 (a)-(g) and (m)-(t), 3.8, 3.9
These contain extra practice and also a few things that are not in the WeBWorK.
• Make sure that you bring your graphing calculator to class next time and every time from now on, so you get practice in using it. We will use it extensively next time.
I believe that I have corrected or fixed all of the links in the previous posts on this blog, but if you find a link in any post that is broken or leads to the wrong thing, please let me know!
Don’t forget, if you get stuck on a problem, you can post a question on Piazza. Make sure to give your question a good subject line and tell us the problem itself – we need this information in order to answer your question. And please only put one problem per posted question!
