Syllabus for Intermediate Algebra

COURSE DESCRIPTION:

This course is designed for students with less than two years of high school algebra. It
is not accepted for college transfer. Students must earn a grade of “C” or higher in
order to progress to transfer-level mathematics courses . This course will cover linear
equations and inequalities; graphs of equations —both linear and nonlinear equations;
slope and equation of lines; systems of equations ; exponents; operations with and
factoring of polynomials ; operations with rational expressions and solving rational
equations; operations with radical expressions and solving radical equations; complex
numbers; functions and graphs; quadratic equations and graphs; exponential and
logarithmic functions. The Texas Instrument TI-83 or TI-84 graphing calculator or a
graphing calculator approved by the instructor is recommended for this course.

PREREQUISITES:


MAT 052 and MAT 061 both with a grade of “C” or higher or assessment

COURSE OBJECTIVES:

Upon completion of this course, the student will be able to:

1. Perform arithmetic operations with real numbers, complex numbers, algebraic
expressions, polynomials, rational expressions, and radical expressions.
2. Solve linear, rational, radical, absolute value, logarithmic and exponential
equations in one and two variables.
3. Solve linear inequalities and compound inequalities in one or two variables.
4. Factor polynomials, specifically binomials and trinomials, as well as be able to
determine those polynomials that cannot be factored.
5. Use various methods to solve quadratic equations, including the quadratic formula.
6. Use graphs to depict solutions to linear equations and inequalities in one and two
variables, as well as systems of equations and inequalities in two unknowns.
7. Use slope, slope-intercept form and/or point-slope form to find equations of lines
and use slope and y-intercept to determine if lines are parallel or perpendicular.
8. Solve systems of equations in two and three variables by substitution or
elimination
.
9. Use laws of logarithms to simplify logarithmic and exponential expressions.
10. Graph conic sections , exponential and logarithmic equations.
11. Apply problem solving strategies and algebraic solutions to problems involving
linear expressions, equations and inequalities, rational equations, radical
equations, and systems of equations.
12. Determine the best method for solving systems of equations and then apply that
method correctly.
13. Determine which law of exponents to apply, when to apply it, and how to apply it
when simplifying exponential expressions.
14. Determine if a problem involves direct, inverse and joint variation and solve
accordingly.
15. Apply problem solving strategies to real life problems and problem situations.
16. Interpret graphs and charts as they apply to real life situations.
17. Graph simple functions, and given a graph, determine whether it is a graph of a
function.

COURSE REQUIREMENTS:

Required Materials. The textbook, along with the usual notebook, paper, pencils,
straightedge, etc. represents the required materials for the class. Your homework
notebook should be loose leaf paper. Calculators will be allowed on all tests. The TI-83
or TI-84 Graphing Calculator (or a graphing calculator approved by the instructor) is
recommended for this course.

Homework. Homework will be assigned for each section of the text that is covered. In
general, homework will not be collected nor graded, but the student should do the
problems assigned as a minimum to attain the skill necessary to do well in the course.
You are responsible for doing at least the selected odd numbered problems in each
practice set. The student should expect to spend about two hours of study outside of
class for each hour of class time.

Attendance. Attendance in this class is both expected and required. John A. Logan
College’s attendance policy will be enforced:

1. Students are expected to attend all scheduled class periods for the courses in
which they are enrolled unless they are participating in a scheduled, supervised
college trip or function. There are no excused absences or minimum number of
class “cuts.” All absences must be made up in a manner acceptable to the
instructor.

2. A student who is absent from a class for three consecutive meetings or who is
excessively absent as defined by the instructor (more than 5 absences), without
prior approval, may be required by the instructor to meet with the department
chair before being readmitted to the class. Students who claim illness as a
cause for excessive absences may be required to present a physician’s
statement before being readmitted to class.
