Knowing a basic understanding of intercept points and how a graph behaves at an asymptote, students can determine the general shape of a rational function by applying the process of elimination. To determine a valid graph, it is necessary to begin at a vertical asymptote and determine how the curve needs to turn in order to connect up to a data point. The purpose of this worksheet is to reinforce the concept of finding a solution by eliminating possibilities, instead of generating remarkably accurate graphs. By knowing these basic principles, a student can begin to learn how to graph a rational function without the aid of a graphing calculator.
