Complete the following questions for our next lesson.

Exercise Set 3D.1 questions 2adgjk

Exercise Set 3D.2 questions 1ade, 2adg, 3ade, 4aef, 5adg

Remember to complete the following questions for our lesson tomorrow.

Exercise Set 3A questions 3 and 4

Exercise Set 3B questions 3–5

Exercise Set 3C questions 3, 5

In our last class we looked at how we could transform the sine and cosine functions to model periodic behaviour. The questions posted during class are listed below. Try to get through to the end of Section 12D, and we’ll continue with these questions during our next lesson.

Exercise 12D questions 2–4

Exercise 12E question 1

Exercise 12F questions 1, 3, 5, 6def, 8

At this point you should have created (and shared with me) a Google Doc that indicates your exploration’s

Your completed draft should be in by the end of the day on Friday next week (**October 20th**).

We’ll have our functions test on **Thursday, the 19th of October**.

In order to prepare for this test, have a look at the questions below. We’ll be spending part of Tuesday’s lesson looking at inverse functions and working on these questions, but it’s a good idea to start these early so you can ask questions if you get stuck.

Review Set 2A questions 1–3, 7, 10, 11

Review Set 2B questions 4, 6, 7

Review Set 2C questions 4, 10, 12

Complete the following exercises before our next class (you may find 5a and 6a useful when answering the other parts of those questions, but if you can answer b, c, and d without doing part a, that’s fine too).

Exercise 10C questions 4, 5bcd, 6bcd, 7, 10c

Your homework for tonight involves work with sign diagrams and rational functions.

Read through Example 9 on sign diagrams on page 68, and see if you can answer the assigned parts of question 2 and 3 (see below) without graphing the given function.

Also read through the textbook section on rational functions (2F), paying particular attention to the discussion of asymptotes. Note that the textbook’s definition of a *rational function* is actually more limited that the (correct) definition we’ve used, which is how they avoid talking about polynomials in this section.

Complete all of the section 2E questions listed below, and as many of the questions below from 2F as you are able.

Exercise 2E questions 1fhk, 2adg, 3agh

Exercise 2F questions 1bc, 2ab

Our next class is the test, so you should have the questions below completed for our lesson on Thursday next week.

Exercise 10A 1abcdghim, 2abc, 3abcdfgh, 4abc

Exercise 10B 1, 5, 7, 8, 10, 13

We’ve now discussed domain and range and had an introduction to composite functions. I suggest that you read pages 64–65, and then complete the questions below before our next class on Tuesday.

Exercise 2C questions 1–3, 4aceik

Exercise 2D questions 3, 5–7
