This course is a survey of mathematical applications of functions. Topics that will be covered
include: Fundamental concepts of algebra, algebraic equations and inequalities ; functions and
graphs, zeros of polynomial functions ; exponential and logarithmic functions, systems of
equations and inequalities. The mathematics of finance will also be covered. Three semester
credits.

COURSE OBJECTIVES:

1. Demonstrate an understanding of mathematical concepts and terminology as evidenced
by the ability to utilize this information to solve both computational and application
problems. Expectations apply, but are not limited to, the major skills of this course as
listed below:
• Solve linear equations in one variable .
Add , subtract , multiply and divide polynomials and utilize this skill in solving
equations.
Simplify expressions with rationale and negative exponents, as well as associated
• Graph equations that are linear, quadratic and other various types.
• Identify equations of linear functions by using the slope-intercept and points-slope
formulas.
• Solve systems of equations via graphing, substitution, and elimination methods .
These skills will be used to find equilibrium in supply-demand problems and
break even analysis.
• Solve linear inequalities and related practical problems.
• Demonstrate knowledge of domain, range and graphing functions.
• Graph quadratic functions and find maximums and minimums.
• Use logarithmic functions to solve practical problems.

2. Apply mathematical concepts and terminology to analyze numerical data, interpret
results, compare options , propose solutions and make effective decisions in situations
requiring quantitative thinking skills.

3. Utilize logic, reasoning, critical thinking skills and problems solving strategies in the
fields of mathematics, sciences, social sciences and business.

4. Acquire fundamental knowledge and skills which are needed for success in related
courses and careers that require quantitative analysis.

ASSIGNMENT INFORMATION

The assignment sheets list the category or type of problems within each section of a chapter, and
the corresponding problem numbers of that category at the end of the section. It is advisable to
do as many of the problems in each category you can until you have mastered those types of
problems. The odd problems have answers in the back of the book for your guidance. Only a
selection of those problems will be graded, they are indicated in the right hand column. Most of
the assigned problems are multiple choice with possible answers given in this workbook. To
choose an answer circle the correct letter at the appropriate position on the answer sheet
provided. In the last assignment there are some tables for you to fill out, please do so in the
