I. Course description
Properties of real numbers; equations and inequalities; functions; sequences; mathematical induction; polynomial, rational, exponential and logarithmic functions; introduction to probability.


II. Prerequisites
Placement or at least a C in MATH104


III. General Education Rationale
Math 105 College Algebra was approved as a QR course in May 2011. Math 105 will help you to refine and extend fluency with algebraic skills. Additionally, the focus of this course is on the conceptual understanding of functions. The course makes the case for using functions to model physical phenomena and simultaneously teaches methods to analyze these functions in a meaningful way. The course presents a catalog of functions – linear, power, quadratic, polynomial, rational, absolute value, exponential and logarithmic functions. By the end of the course students should know the basic properties and graphs of these functions along with using them as models for real world applications.
For these reasons, Math 105 will count for the Quantitative Reasoning Requirement in the general Education program Education for Participation in the Global Community.


IV. Goals of the course
A primary goal of Math 105 is to prepare students for calculus. However, this is a terminal math course for certain students whose program does not require Calculus.

V. Textbook
Larson, College Algebra: Real Mathematics, real People, 6th Edition (Custom edition).

VI. Technology
This course requires that all students have a graphing calculator. However, the class will be run such that any graphing calculator is adequate. The Math department recommends TI 84. I can help you with the calculators I am familiar with (always Texas instruments but not Casio). However, the tutors in the Math Lab (4th level of PH) may be able to help with various models of graphing calculators.

VII. Evaluation
There is one midterm and a final exam. There are daily short quizzes from the material presented during that week.

Midterms: November 7, October 3
Final: December —to be announced
Quizzes: every week
Quizzes have attendance value; they can’t be made up later!

All exams are hold during the regular class sections.

The final grade in this course is computed using the following weights:

Midterm I 20 %
Midterm II 20 %
Final 20 %
Quizzes 40 %

The cut-offs for the final grade in this course will be calculated as follows:

A 95 %
A- 90 %
B+ 85 %
B 80 %
B- 75 %
C+ 70 %
C 65 %
D 60 %
E <60 %
