Course Description:

Pre-requisite: MAT1033 or MAT 0025C with a grade of C or better, or satisfactory score on entry assesment test. This course is based on the study of functions and their role in problem solving. Topics include graphing the linear, quadratic, and exponential families of functions and inverse functions, polynomial and rational functions and their graphs, systems of equations and variation. Students will be required to solve applied problems and communicate their findings effectively. A minimum grade of C required if MAC 1105 is used to satisfy Gordon Rule and general education requirements. Technology tools will be utilized in addition i.e the course will completely integrate graphing technology with the standard topics of College Algebra. Problems will be solved using analytic, numerical and graphical techniques. This course reinforces the following CLAST and Valencia graduate competencies.

CLAST Competencies:

1.English language skills

2.Reading/Writing Skills

3. Arithmetic skills

4.Geometry /Measurement skills

5.Algebra skills

6.Logical reasoning

Valencia Core Competencies:

Valencia desires their graduates to possess and demonstrate a set of global competencies including the ability to think, communicate, value and act.

In an effort to help you acquire and improve upon your ability to demonstrate these competencies this course will include activities that require you to:

Think clearly, critically and creativelyto analyze the data , formulas, procedures, conclusions and interpretations

Communicate with others in written and verbal form through the content of the course material

Make reasoned value judgements and responsible commitments.

Act purposefully, reflectively and responsibly to develop your knowledge, skills and values.

Due to the nature of these global competencies many problems and activities will be presented in the context of an application. These applications will require students to select appropriate information from the problem and communicate effectively how to arrive at an appropriate solution for the problem. This course reinforces the arithmetic and many of the algebra CLAST competencies, teaches several of the algebra CLAST competencies not taught in earlier courses, and helps build the competencies expected of a Valencia graduate. Additional information is available in the College Catalog (http://valenciacc.edu/catalog/04-05/default.htm on page 14).

Attendance :

Regular attendance and class participation are significant factors that promote student success in this course. Students are expected to attend every class, be punctual, and complete all assignments. Students are responsible for all work presented when they are absent. Students are responsible for any announcement made in class, whether or not they are present. Excessive absences – more than 10% at any given time - without adequate excuse may result in withdrawal from the course. Students are required to remain in class for the whole period, unless prior permission to leave early has been granted by the instructor; it is disruptive to depart while class is in session.

Tardiness :

All classes start at the time indicated on the class schedule. Being late to class is a disruption and is discourteous to the professor and the rest of the students. Two tardies equals one absence.

Class Participation :

Students are encouraged to participate actively and ask pertinent questions during class. Courtesy will be observed at all times. Students must do their own work; there are no exceptions. Students who plagiarize or cheat in any way risk dismissal from class and expulsion from the college.

Cell Phones :

Students are required to turn off all cell phones and pagers before the beginning of class. If a cell phone or pager vibrates or is audible, the student may be asked to turn it off or leave for the remainder of the class. If there is an emergency situation warranting the use of a cell phone or pager during class time, the student must notify the professor in writing prior to the beginning of class. During a testing situation, if a cell phone or pager vibrates or is audible, the student’s quiz, test, or examination will be collected and the student will be asked to leave without an option for completion

Academic Dishonesty :

All forms of academic dishonesty are prohibited at Valencia. Academic dishonesty included, but is not limited to, plagiarism, cheating, furnishing false information, forgery, alteration or misuse of documents, misconduct during a testing situation, and misuse of identification with intent to defraud or deceive. Sanctions available to the professor should a violation occur are described in the Valencia Student Handbook or online at

Withdrawal :

The College has initiated withdrawal procedures and timelines in response to legislation/rules adopted by the state legislature and State Board of Community Colleges. The deadline to withdrawal from this course is in the current catalog, and is also available online at http://valenciacc.edu. After that date, if you withdraw or are withdrawn from the course, you will be assigned either a “WP” (withdrawn passing) or a “WF” (withdrawn failing). Additional information is available in the College Catalog (http://valenciacc.edu/catalog/04-05/default.htm on pages 62 - 65).

Withdrawing before withdrawal deadline will result in a grade of "W". After that date withdrawing will result in a "WP" or "WF" grade based on the work though the last day of attendance.

Not taking the final exam results in an automatic grade of "F".

Students with disabilities :

“Students with disabilities who qualify for academic accommodations must provide a letter from the Office for Students with Disabilities (OSD) and discuss specific needs with the professor, preferably during the first two weeks of class.The Office for Students with Disabilities determines accommodations based on appropriate documentation of disabilities. The East Campus Office is located in Building 5, Room 216."
