Quick correction - Pg. 3, The function P(x)= x^4+5x^2+4 SHOULD BE P(x)= x^4 - 5x^2+4

__**Week 1 (Sep 21- 25):**__ I have a question about the last function's domain, the f(x)=x^x, it says x>0, but cant the domain also include negative numbers as long as they are whole numbers?? for example, -1, -2, -3, -4, -5, -6... gives you a real value for f(x). -Ho Jun Eom (Oct 5, 2009) But then again, we know that negative integers work and non-integer, negative rational numbers don't, but what about irrational numbers? hm....... it seems to be a function difficult to deal with. -Ho Jun Eom (Oct 5)

- Craig Kung Graph Transformations for the function f(x) = x4. Best viewed at about 60-70% of the original size, with multiple pages viewable. Black line indicates the original graph, red line indicates the transformed graph.

- Craig Kung Homework from a while ago, describing transformations. You might need to zoom in for graphs.

__**Week 2 (Sep 28- Oct 2):**__ Important Terms for Polynomials w/ Examples: - Jessica Leung

Answer:** You can download geometer's sketchpad in a trial version for home. You can't save or print anything, but you can just press "print screen" on the keyboard and then crop the picture so you can put it in a note on the wiki. [] That's the version I downloaded. -Kami
 * Question: Any reliable & free online** **/downloadable graphing programs out there?

-Christina
 * Answer:** I have geometer's sketchpad on my computer I got it from my school I can save it on a USB and bring it tomorrow if you still need it. Graphmatica is also suppose to be good.

Exponent Laws November 20th, 2009 Log Practice Questions P = (1+r)t instead of **2** = (1+r)t so sorry if that caused some confusion!
 * November 27, 2009**
 * USE AT OWN RISK...hasn't been checked with Stewart.
 * For question 5, I accidentally wrote
 * One of the questions answer should've been 903 (It had to do with base e, near the end) instead of 7800 something. So don't freak out =)
