Topics:
• Some problems from the textbook on finding domains of functions defined by formulas: Exercise 3.6(a-d and f)
• Another example of a difference quotient: Example 3.3(b)
• Functions which are defined by graphs: Session 3 Examples 3.6-3.9 and 3.12
It is extremely important that you understand how to read graphs and how to identify the input and output values. Study these examples!
Homework:
• Study the examples discussed in class: make sure that you understand the notation and vocabulary that is being used.
• Make sure that you have signed into WeBWorK (and do the assignments) and that you have joined the Piazza discussion group. I am directing Piazza to re-send the invitation to those students who have not yet activated their Piazza accounts.
• You may join OpenLab and join this course on OpenLab if you wish. It is not required: you can read this blog without joining. But membership has its benefits!
• In addition to the WeBWorK, do the following problems from the textbook:
Session 2, Exercise 2.5(d, e) and 2.8
Session 3, Exercise 3.7
• Make sure to bring your graphing calculator to the next class and every class from now on. We will be learning how to use it in these coming lessons.
