College Algebra

I.     Course Prefix/Number: MAT 140

       Course Name: College Algebra

       Credits: 3 (3 lecture; 0 lab)

II.    Prerequisite

MAT 110 or the equivalent with a minimum grade of C or appropriate score on the Mathematics Assessment Test; and MAT 080 or geometry proficiency.

III.   Course (Catalog) Description

A study of the following functions and their graphs: polynomial, rational, exponential, logarithmic, and special functions; systems of equations and inequalities, sequences and series, and the binomial theorem.

IV.   Learning Objectives

1. Classify functions and their graphs, and identify their domain and range.
2. Identify and apply transformations of graphs.
3. Solve linear and non-linear equations, and systems of two equations.
4. Solve polynomial and rational inequalities algebraically and graphically.
5. Sketch the graph of polynomials using zeros and end behavior.
6. Sketch the graph of rational functions using zeros, asymptotes, and end behavior.
7. Find, graph, and interpret the inverse of a function.
8. Graph exponential and logarithmic functions, and use their properties to simplify and solve equations involving them.
9. Model and solve applications using the elementary functions studied in the course.
10. Use technology to graph, evaluate, and interpret functions, and to solve equations and inequalities involving them.

V.    Academic Integrity

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Details of the Code of Academic Conduct can be found in the Student Handbook.

XI.   Other Course Information

Individual instructors will establish and announce specific policies regarding attendance, due dates and make-up work, incomplete grades, etc.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.
