Course (Catalog) Description:

This course focuses on the study of functions including polynomial, rational, exponential, logarithmic and trigonometric functions. Additional topics include the conic sections, series, parametric equations, and polar equations. Use of technology is integrated throughout. 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. 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. 0 8. Graph exponential and logarithmic functions, and use their properties to simplify and solve equations involving them. 9. Classify and sketch the graphs of conic sections. 10. Analyze, evaluate and graph trigonmetric functions and their inverse functions. 11. Solve trigonmetric equations, and prove and apply trigonometric identities. 12. Solve trigonometric applications including polar equations, vectors, and parametric equations. 13. Expand, calculate and evaluate series and sequences. 14. Model and solve applications using the elementary functions studied in the course. 15. Use technology to graph, evaluate, and interpret functions, and to solve equations involving them. V.

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. VI. B.
