VIDEO: Algebra Applications: Rational Functions 
In this episode of Algebra Applications, students explore various scenarios that can be explained through the use of rational functions. Such disparate phenomena as submarines, photography, and the appearance of certain organisms can be explained through rational function models. This video includes a Video Transcript: https://www.media4math.com/library/videotranscriptalgebraapplicationsrationalfunctions 

VIDEO: Algebra Applications: Rational Functions, Segment 1: Submarines 
In spite of their massive size, submarines are precision instruments. A submarine must withstand large amounts of water pressure; otherwise, a serious breach can occur. Rational functions are used to study the relationship between water pressure and volume. Students graph rational functions to study the forces at work with a submarine.

VIDEO: Algebra Applications: Rational Functions, Segment 2: Biology 
All living things take up a certain amount of space, and therefore have volume. They also have a certain amount of surface area. The ratio of surface area to volume, which is a rational function, reveals important information about the organism. Students look at different graphs of these functions for different organisms.

VIDEO: Algebra Nspirations: Rational Functions and Expressions 
After briefly reviewing the concept of inverse variation, this video explores Boyle’s law, a real world example of an inversely proportional relationship between pressure and volume of a gas. Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, it goes on to examine similarities and differences among rational functions and numbers. Finally, it takes a look at rational functions graphs and ends with a delightful example merging Euclidean and analytic geometry, thanks to the TINspire technology. Concepts explored: functions, rational expressions, rational functions, asymptotes This video includes a video transcript: https://media4math.com/library/videotranscriptalgebranspirationsrationalfunctionsandexpressions A Promethean Flipchart is available for this video: https://www.media4math.com/admin/content?title=promethean&type=library_asset&status=All&langcode=All
