Alcohol in Your Body (Rational functions)

The functions that model the process of the elimination of alcohol from the body serve as an introduction to a study of rational functions at an intermediate algebra level. The lesson focuses on graphs of the functions with an emphasis on interpretation of the horizontal and vertical asymptotes in the context of elimination of alcohol from the body. Other mathematics involved is algebraic manipulation of the rational functions, solution of equations with rational expressions, realistic domain of a function, inverse functions, and equilibrium state of a dynamic process.
