Students explore end behavior of rational functions graphically, algebraically, and by using tables. They will use multiple representations to look at values a given function approaches as the independent variable goes to positive or negative infinity. Tools are provided which support them in using a graphical approach, evaluating functions at different values, and using a function equation to find the end behavior of a rational function.

Download the attached PDF and look over the information on the first page. Download and distribute the attached .tns file and Student Worksheet for use during the activity.

Discuss the material from the activity pages and worksheet with students as needed.

Encourage students to summarize what they have learned from completing the activity. If desired, discuss the extension with students.
