Algebra II: P. 109
Elementary Functions:Block A - Worksheet, all 4 problems.
Block C. P.106 41, 44, 45 -- try 45, do your best, I'll try to post some more info later if I can. or here
I cannot say enough, if you are struggling, come in for help! I can make myself available before school, during majors and occasionally after school by appointment. If you are a real early bird, let me know and I will bring you up before 7:15 if you plan on working.
Ten basic functions:
y=x
y=x^2
y=x^3
y=1/x
y=sqrt(x)
y=ln(x)
y=
For 45B: understand that f(x+y)=f(x)+f(y) means that if you pick any two numbers (let's just pick 6 and 33) setting x=6 and y=33, then plugging 6+33 ( which =39 ) into the original function would give you the same value as plugging 6 into the function, getting your answer, plugging in 33 to the function, taking that answer and adding to your original answer. Let's try it with x^3:
f(x)=x^3
f(39)=39^3 = 59319
check if f(6) + f(33) is the same
f(6)=6^3 = 216
f(33)=33^3 = 35937
f(6)+f(33) = 216 + 35937 = 36153 which is not 59319, so the answer to b is not f(x)=x^3
Similarly, d means to take 6*33, input that to the function, then check if that is the same value as above (namely, f(6) + f(33) )
Hope this helps!

Algebra II: Nice job in the lab folks, no new homework, but last night's work is worth double! Be sure you're done!!!
Elementary Functions: Homework for both blocks is P.105 1-20 all. The first 10 are matching the 10 basic functions (some slightly modified) from the project to their graphical representations. Be sure you can identify functions from either model (algebraic or graphical). The last half of the assignment talks about the properties of the functions.
Link for homework (again, megaupload makes you type in 3 characters to verify you are downloading... please ignore any ads, I wish I could do this free somewhere else.)
Finally, this is mostly for parents, but if you want a grade report to be emailed to you, please send me email (so I have your contact information) or comment to this post and I can add you to my list.

Algebra II: P. 102 18-32, 39-40
Elementary Functions: No homework, either block
Block A, be sure you're working on your projects, I will not be giving you much class time to finish -- this is up to you!
Block C, you have your test back, if you're still scratching your head, COME IN!!!! I'm at school by 6:30 -- you are allowed up at 7:15, I will be happy to spend time with you on any topic. If you would like to retake a test, my general policy is that you have scored 60% or below (up to 70% with permission) on your first attempt, and you prove to me that you have done work to better understand the topic(s) you weren't successful with. I will award you the 2nd score (higher or lower) after I evaluate your test. You MUST see me if you plan to do this, and you must tell me at least 12 hours in advance of taking the retake (in person, or email runderwood2@pghboe.net).
Good luck.

Algebra II: Test will be Tuesday, be sure you can do problems from each of the sections in chapter 1. Test topics should include simplifying expressions, solving equations, solving equations for a given variable, solving and graphing inequalities and absolute value equations and inequalities.
Elementary Functions: Test will be strikingly like the homework/classwork, I hope you followed along. First, I would look at the key ideas on page 55 and be sure you can say a good sentence or two about each concept. Next, in Properties, Theorems, and Formulas the list, be sure you know and understand the distance formula, midpoint formula, and quadratic formula. Be sure you are comfortable with interval notation and have some idea of domain and range. Finally, equations of circles are fair game, so you should know how to write the equation of a circle given a point and radius or work backwards given an equation, finding the center and radius.

34, 35,64, 66-69
Elementary Functions: P. 53 do 1, 4, 7, 10, 13, 31, 35, and we will talk about 38 in class so be sure you've looked at it and can follow along.
To those that have not taken the assignments seriously, I hope you reconsider their importance. Yes, the assignments only make up 15% of the total class grade, however, quizes and tests are drawn directly from the assignments, so homework is your best chance to practice.

It may seem harsh, but that is only 16 problems!
Elementary Functions:
Block A: Make sure you're comfortable with linear and be ready for quadratics tomorrow.
HW: p. 37 37-40
Block C: We're getting a little behind schedule, but it's better to be sure that factoring isn't an issue, and that we can knock this out early.
PDF is big, so try either tonight/tomorrow link, they are two different servers but the same file
Tonight p.45 1-18all
Tomorrow will be the difference between tonight and p.45-46 1, 4, 7, 14, 19, 45, 55, 59, and 62

Algebra II: No homework -- quizzes look pretty good, I'll have them back to you this weekend.
Elementary Functions: Block A - finish P.18, 37 &38a - it's easier to write here than scan:
37. Prove that the figure determined by the points is an isosceles triangle: (1,3),(4,7),(8,4)
38. Prove that the diagonals of the figure determined by the points bisect each other:
(-7,-1),(-2,4),(3,-1),(-2,-6)
Blocks A & C : I realized I haven't posted grading rules for you, sorry!
Classwork 15%
Homework 15%
Projects (take home & in class) 10%
Assessments 60% (Quizes 15%, chapter tests 45%)
If you think your last quiz was poor, there will be plenty of opportunities to redeem yourself.
Also, remember the 3-point circle problem? Check this out: http://www.delphiforfun.org/Programs/Math_Topics/circle_from_3_points.htm
Have a great weekend!
