Course Outline for College Algebra

Catalog description (2006-2009 Catalog):

In-depth study of linear and quadratic functions, their graphs and transformations; inverse
functions; modeling; polynomial functions and their graphs; and conic sections. The
graphing calculator will be used throughout the course. 4 lecture hours

Is the course New, Revised or Modified? Revised

Required texts/other materials

1. Text: College Algebra: An Early Functions Approach, by Blitzer
Publisher: Pearson Prentice-Hall
2. Calculator: A graphing calculator is required. Recommended: TI-83, 84 or 86.
Calculators with symbolic manipulation are not permitted.

Information resources:
• The college library has many books, CDs and videos available.
• MyMathLab is an on-line companion to the text offering a lot of practice.
• The Learning Center has tutoring and help available to the students.

Course Competencies/Goals:

Students will be able to demonstrate the ability to:

A. recognize and work with functions and function notation.
B. determine the inverse of a function, if it exists, and the relationship that exists between
and function and its inverse both algebraically and graphically.
C. solve algebraically and graphically linear and quadratic equations and inequalities.
D. explain the relationship of real numbers to complex numbers and perform algebraic
operations with complex numbers.
E. recognize common graphs, graphing transformations and find pertinent information from
the graphs.
F. define a polynomial and explain the characteristics of the graph of a polynomial
including end behavior, degree and multiplicity of zeros.
G. perform the algebra of functions including the composition of functions.
H. recognize algebraically and graphically the conic sections and find pertinent information
about them.
I. demonstrate expertise in sketching functions and in using the graphing calculator to graph
functions, to enter expressions on which mathematical operations are to be performed
properly, and to find a linear or quadratic regression for given data.
J. solve word problems (or models).

Course-specific General Education Knowledge Goals and Core Skills:

General Education Knowledge Goals:
