Important Announcement: Test 1 is on Thursday, 1 October. The test will cover finding domain of functions, Sections 1.5, 1.6, 1.7 and maybe Section 2.1.
I will accept Project 1 on Tuesday, 29 September; however, I will deduct 5 points from the total.
The Quiz on Project 1 will be on Tuesday.
Today, we covered a few more examples of composition of functions. We discussed how to evaluate composition of functions using graphs of f(x) and g(x). We also talked about inverse functions: the compositions, f(f -1(x)) = f -1(f(x)) = x; the graphs of inverse functions are reflections over the y = x line. We will finish Section 1.7 on Tuesday and finish Section 1.5 on Tuesday.
The next homework assignment is due on Tuesday, 29 September 2009 and will consist of the following:
Section 1.6: 61-70;
Section 1.7: 9, 12, 14, 15, 19, 21-24, 111-114
NOTE: If you have already completed some of these questions and submitted them today, then please do not re-do the questions – I will provide you with the appropriate credit.
