Algebra Series  Concepts and Formulas™
Rational Functions 3 and Variations (ALGCF28)
This sheet provides a comprehensive review of all of the most important topics, concepts and formulas covering rational functions and variations, explained in detail, with detailed illustrations. Unlike charts and notes, this Concepts and Formulas™ sheet anticipates and answers questions about how to use the concepts  how to solve problems with them, it doesn't just list facts and formulas. There is even an example, or two, for each concept, to help you to nail down the central ideas.
