College Algebra
Courses Description:
This course is a functional approach to algebra that
incorporates
the use of technology. Emphasis will be placed on the study of functions, and
their
graphs, inequalities, and linear, quadratic, piece-wise defined, polynomial,
rational,
exponential and logarithmic functions. Appropriate applications will be included
Text: College Algebra by Lial, Hornsby and Schneider (Addison/Wesley).
NOTE: Students can either use the 10th edition
available from the publisher OR the
West Georgia edition available from the bookstore.
Learning Outcomes: Students should be able to demonstrate:
1. An understanding of the equations of circles and
lines
2. An understanding of functions and how to graph functions
3. An understanding of operations on functions including function
composition
4. An understanding of polynomial graphs, including intercepts and
end -behavior
5. An understanding of how to find the zeros of a polynomial and how to
factor polynomials
6. An understanding of inverse functions and how to find them graphically
and algebraically
7. An understanding of the properties of exponential and logarithmic
equations
8. An understanding of how to solve exponential and logarithmic equations
9. An understanding of how to solve a system of equations
