Required Text:  Precalculus 5th Edition by Sullivan & Sullivan,

Check out the Solutions manual for this course before purchasing it to see if the book meets your needs.  

Course Description:  This course is an in-depth study of functions.  We will study linear, quadratic and higher order polynomials, rational functions, zeros of polynomial functions and their theorems.  We will analyze functions’ algebraic and geometric properties.  Special emphasis will be placed on application problems and the use of graphing calculators.  I will be demonstrating on a Texas Instrument 89 (TI 89) graphing calculator.  You may rent a TI-89 from the college with a deposit and fee per quarter.  Please see  me if you have any questions.

Student Learning Outcomes:
1. Produce and interpret graphs of functions and relations.
2. Apply techniques to solve polynomial and rational equations and inequalities.
3. Model real life situations using algebraic methods.
4. Simplify algebraic expressions using skills obtained in the course.

Prerequisite:  A grade of "C" or better in Math 154, or equivalent or appropriate skills demonstrated through the Math Assessment process.

Students with disabilities must identify themselves to me within the first two weeks of class.

Accommodations for Students with Disabilities: Students requiring accommodations for a certain disability that may affect class performance are requested to schedule with a staff member at the Disability Resource Center to discuss this during the first week of the quarter so that appropriate arrangements can be made.

* Course materials available in alternate format. 

Grading:  Your class letter grade will be based on the usual grading scale:

A:  90% and above,    B: 80-89%,     C: 70-79%,        D: 60-69%,             F: 59% and under.

            Homework                                          100 pts.                                              

            4 Quizzes                                             100 pts.

            Midterm Exam 1                                  100 pts.

            Midterm Exam 2                                  100 pts.

Comprehensive Final Exam                100 pts.

            Total                                                    500 pts

 

Homework:  The homework assignments to be turned in for credit are due in class weekly.  They are found in the lecture schedule following each section.  Each homework assignment is due in class and is considered late if it is not turned in.  If you will be absent, either turn in the homework assignment early or have someone turn in the homework assignment for you.  Late homework receives reduced credit.  Your work must support your answers.  Each homework section is worth 10 points.

Quizzes:  There are no make-up quizzes.   I give five quizzes but only four are counted so your lowest quiz score will be dropped. 

Midterm Exams:  You must notify me before an exam if you will miss the exam (577-0414).  Exams must be made up within 3 school days after the scheduled date.  You may take an exam up to 3 school days before the scheduled date.  Arrangements must be made with me one week in advance.

Please come see me if you do not understand these policies.

In this class, it is your responsibility to drop the class in order to avoid an unwanted grade.  You must go to Admissions & Records.

Friday, October 2, 2009 is the last day for refunds.

Friday, October 16, 2009 is the last day to drop with no record.

Friday, November 06, 2009 is the last day to withdraw with a “W” grade.
