Modeling Rational Functions by Graphing

The video tutorial explains how to model rational functions by graphing. It begins with an introduction to rational functions, using tables and equations. A practical example of sharing parking costs is used to illustrate the concept, showing how the cost per person decreases as the number of people increases. The tutorial then covers graphing rational functions, highlighting that the graph never touches the axes and can include negative numbers. Finally, a real-world problem involving a concrete mixer is modeled using rational functions, demonstrating how to determine the depth of concrete based on the area covered.
