Class Announcements

11-23	Get a Final Exam Study Guide either by printing it or by buying it at the bookstore (it's under $2). Bring this to class with you on Dec 6, 7, & 8. If you show up all 3 of these days then I'll drop a 4th homework score.
11-22	I've posted some tips for calculating your grade here.
10-19	Starting next week I will be in the tutoring room Wednesdays at 11 instead of Monday at 11.
10-11	Attendance is mandatory every day but it is especially mandatory on Thursday 10-14. I will provide you with a grade report.
10-11	Withdraw deadline is Friday 10-15.
9-7	Office hours on Tuesday Sept. 7 have been switched to Thursday Sept. 9 from 9 to 10.

Homework & Quizzes

Typically, there will be 2 homework assignments per week with homework due two class periods after it is assigned. Students are encouraged to attempt homework on the day that it is assigned and to ask homework-related questions during the following class.

Homework Policies

Homework will only be accepted at the beginning of the class period in which the homework is due. Late homework will not be accepted. Exceptions may be made in the case of an unavoidable absence with justifying documentation and, when possible, if prior approval is obtained from the instructor.
Show your work. Credit will not be given for answers which do not clearly show the necessary steps for obtaining the solution. Answers should be simplified as much as possible (e.g., reduce your fractions)
Homework must be stapled and legible.
Homework assignments will be posted to the class web-site.
Students are required to read the appropriate section prior to attempting homework. Some material may not be covered in class; the student will be expected to learn this material on his/her own. Reading math text is an acquired skill which requires practice; it is essential to your success in this and future math classes.
Students may discuss or work together on homework but each student must write his/her own solutions. Students may also discuss homework on the class listserv mailing list.
No extra credit will be available at any point during the semester.

Homework Grades

Each homework assignment will be worth 15 points. At the end of the semester the sum of all homework grades will be scaled down to 150 points (e.g., if there were 20 assignments and you scored 260 out of 300 possible points then your points would be scaled to 130 out of 150).
Not all homework problems will be graded. Selected homework problems will be graded for each assignment. Up to 5 points will be awarded for attempting every problem. Up to 10 points will be awarded for graded problems. Typically, 5 of the assigned problems will be graded.
One of your homework assignments is to visit the instructor at least once during his office hours. The student should come prepared with a math-related question.
Each student’s 3 lowest homework grades will be dropped at the end of the semester.
Please review graded homework. The feedback which you are given is essential to the learning process and will help to prepare you for exams.

Quizzes

There will be 4 exams throughout the semester. There may be additional quizzes given throughout the semester. Grades from quizzes will be factored into the final Homework grade. These will not be pop quizzes. Course policy for missed quizzes is the same as that for missed exams (see “College Algebra Course Policy”)

See pg AP-14 in the back of the textbook for a description of this. - 4.1 #68 is NOT a polynomial so you cannot use the rules described on the bottom of pg 228. Think about the definitions: Is f(x)=f(-x)? Is f(-x)=-f(x)?

6	9-16 (Thur)	9-21 (Tues)	- Read pg.115-116 on Interval Notation. In some cases, this may be used as an alternative to Set Builder Notation. - Textbook pg. 120: 21, 24, 26, 27, 29 - Textbook pg 134-136: 8, 24a, 24b, 33, 37, 38, 45, 46, 48, 49, 51* - Workbook pg. 53-54: all.
