I apologize for the outage on the site yesterday and today. Lamar University is in Beaumont Texas and Hurricane Laura came through here and caused a brief power outage at Lamar. Things should be up and running at this point and (hopefully) will stay that way, at least until the next hurricane comes through here which seems to happen about once every 10-15 years. Note that I wouldn't be too suprised if there are brief outages over the next couple of days as they work to get everything back up and running properly. I apologize for the inconvienence.

Absolute Value – A couple of quick problems to remind you of how absolute value works.
Radicals– A review of radicals and some of their properties.
Rationalizing– A review of a topic that doesn’t always get covered all that well in an algebra class, but is required occasionally in a Calculus class.
Functions– Function notation and function evaluation.
Multiplying Polynomials – A couple of polynomial multiplication problems illustrating common mistakes in a Calculus class.
Factoring– Some basic factoring.
Simplifying Rational Expressions– The ability to simplify rational expressions can be vital in some Calculus problems.
Graphing and Common Graphs – Here are some common functions and how to graph them. The functions include parabolas, circles, ellipses, and hyperbolas.
Solving Equations, Part I – Solving single variable equations, including the quadratic formula.
Solving Equations, Part II – Solving multiple variable equations.
Solving Systems of Equations – Solving systems of equations and some interpretations of the solution.
