Understanding Asymptotic Behavior of Functions

The video tutorial explores the concept of asymptotes, focusing on horizontal and vertical asymptotes. It discusses how to identify these asymptotes in rational functions and examines the behavior of graphs near these lines. The tutorial also covers intercepts and domain restrictions, emphasizing the differences between rational functions and parabolas. The instructor uses examples to illustrate these concepts, preparing students for more advanced calculus topics.
