Horizontal and Vertical Asymptotes of Graphs of Rational Functions

Curated and Reviewed by Lesson Planet

Get close to your favorite line. Scholars use end behavior to help find horizontal asymptotes. With the understanding of domains of rational functions, learners find vertical asymptotes and then use graphing calculators to verify the asymptotes found. Pupils practice their skills and sketch graphs of the rational functions with exercises to finish the 14th installment of a 23-part Pre-calculus unit.
