Required Text:  Precalculus 3^rd Edition by Sullivan & Sullivan III,

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.  Parts of the testing do not allow graphing calculators.   Please talk to me if you have any questions.

Course Objectives:  Students will be able to:
1. exhibit a proficiency in the topics covered in the course;
2. engage in logical and critical thinking;
3. read technical information; and
4. demonstrate the solution to problems by translating written language into mathematical statements, interpreting information, sketching relevant diagrams, analyzing given information, formulating appropriate math statements, and checking and verifying results.

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

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                                           15 %                                       

            4 Quizzes                                                10 %

            Midterm Exam 1                                 25 %

            Midterm Exam 2                                 25 %

Comprehensive Final Exam                25 %

            Total                                                    100 %

Practice Problems are not to be turned in for credit.  They are to help you understand the material and prepare for quizzes/exams.  The Practice Problems are found on the last page of the syllabus. 

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 that is turned in within one week of the due date receives half credit.  Homework turned in after this receives no credit.  Your work must support your answers.

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, with a penalty of 10%.  You may take an exam up to 3 school days before the scheduled date without penalty.  Arrangements must be made with me one week in advance.

Parts of the testing (quizzes, midterms and final exam) may have problems that do not allow for graphing calculators.  I will tell you when these will occur.

Please come see me if you do not understand my 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, Jan 14, 2005 is the last day for refunds.

Friday, Jan 28, 2005 is the last day to drop with no record.

Friday, Mar 4, 2005 is the last day to withdraw with a “W” grade.

Each homework section is worth 10 points.
