Modeling Rational Functions by Graphing

The video tutorial explains how to model rational functions by graphing. It begins with an introduction to rational functions, often expressed as x times y equals a constant. The tutorial uses a parking cost example to illustrate how the cost per person decreases as the number of people increases, demonstrating the inverse relationship. It also covers graphing these functions, showing that the graph approaches but never touches the axes. The tutorial concludes with a concrete mixer problem, modeling the relationship between area and depth using a rational function.
