Paul's Online Notes: Lamar University: Paul's Online Notes: Algebra: Rational Functions

Sometimes graphing rational functions can feel a little "irrational." Starting with the basics, learners work their way through the pieces of these graphs and finish off with an application question. 

No laundry or cooking dinner here: these parent functions are all about math. Every graph you could think of from basic linear functions to the hyperbolic arccotangent function are included. With 40 parent functions, the worksheet...

Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.

This video focuses on rational expressions and completes Sal's lecture series on working with and solving this particular type of equation. Its length would be ideal for a computer lab visit or homework assignment (in conjunction with a...

Put your math pupils’ division and algebra skills to the test with this video, which introduces the concept of polynomial division. Sal's examples increase in complexity as the video progresses, allowing viewers to see how basic skills...

Detailed math tutorial features notes and examples that take a look at the process of partial fractions and finding the partial fraction decomposition of a rational expression.

Detailed math tutorial features notes and examples that take a look at graphing functions including several examples of graphing piecewise functions.

Detailed math tutorial features definitions and examples that take a look at relations and functions, function notation, the domain and range of a function, and piecewise functions.

Detailed math tutorial introduces logarithm functions giving the basic properties and graphs. Also, discusses how to evaluate some basic logarithms including the use of the change of base formula, the common logarithm, log(x), and the...

Provides examples of applications of exponential functions involving compound interest and exponential growth and decay, and an example of an application of a logarithm involving earthquake intensity.
