Ch 3: Exponential and Logarithmic Functions

We start with an explanation which is both review and a new way of looking at exponential functions.
Some of the 12/04 homework problems involve regression. Here is a document that will remind you how to do them on the calculator. The example uses a quadratic but I have faith in your ability to extend the information to the exponential and logistic regressions.

Conjugate Proof Exemplars

Here is a link to the good/better/best proofs.  It is worth your while to understand what makes one proof better than another (for the good of your future proofs).

We are back in the Demana book with Chapter 2: Polynomials. The beginning of the polynomial chapter is mostly review - and then it gets complex (literally!).  The chapter includes how complex numbers relate to polynomial functions.  We will be spending a couple of weeks on polynomials and complex numbers.  Quick, skill-based check-in quizzes could happen at any time after the first three days of basic instruction so stay on top of your homework.

I may give homework problems on complex zeros from the old edition of the book which used to take two sections to cover the material.  I like some of the problems that were deleted in the new edition so you may be given copies of the pages.

I will be out on November 7th and 8th so I may change the schedule a bit.  Check back.

Getting Started

After the pretest, we start by discussing Function Vocabulary. After a brief foray into chapter 10 for an explanation of limits, we continue looking at function details.

(The dates below are for the E-Block class. All the Wednesday dates are Thursdays for G-Block.)

9/02 Labor Day
9/03 Brain Awakening Problems (E-Block only)
9/04 Rosh Hashanah - no school
9/05 Pretest (based on summer work - I will be out)

9/09 Domain and Range (with some new notation)
        HW finish handout and read section 1.2
9/10 Extrema, Increasing/Decreasing, Odd/Even Symmetry CW p.97/79
        HW p.94-95/1-4, 9-19 odd, 25-33 odd, 47-53 odd
9/11 Limits: definition, notation, evaluation
        HW p.763-764/1-23 odd, 26, 31, 37, 49, 61, 71
9/12 Half Day C B A G
9/13 Asymptotes, Holes, and Continuity
        HW p.95-98/35, 37, 39, 55-61 odd, 67, 68, 81, 86

9/16 Twelve Basic Functions (section 1.3)
The twelve basic functions are the ones we will come back to over and over during the course of the year. Several of them are related to each other in a variety of ways. You need to be completely familiar with their graphs and properties. We start with an exploration.
        Exploration and CW; HW p.106-109/13-28, 45-55 odd, 64, 65, 68, 69
        (Hint: use a and b instead of x and y for problem 69 - it is easier to understand that way.)
9/17 Functions operations (section 1.4): addition, subtraction, multiplication, division and (perhaps most importantly) composition. The big issue is the change of the domain for the new function. Try the Exploration on page 112 (if we don't finish it in class - it is good for you to think about what composed functions can turn into). There is also the issue of non-function relations and the functions implied by their equations. Ask again if the explanation in class and homework doesn't clarify the issue for you.
         HW pp.116-118/5, 7, 12-42 by 3's, 51-55
9/18 More Problems on Composition
         HW finish worksheet
9/20 Function Descriptions and Combinations HW finish worksheet

9/25 Big Review Packet (Day 2)
9/27 Test of Function description and manipulation

Welcome...and a note

Hello!  Welcome to Honors Advanced Math.  The year is one with many new kinds of mathematics - some of the most science and engineering based math you will learn.  Please remember to look over the summer assignment.  The pre-test will be on Friday, September 6th in class.  (Remember that this test is a diagnostic tool and doesn't count for a grade.  Do the summer assignment and you will be fine!)
