Analyzing Rational Functions and Asymptotes

The video tutorial explores a rational function, analyzing its vertical and horizontal asymptotes, domain, and holes. The instructor uses algebraic methods to determine the correct graph representation, emphasizing the use of limits and factoring. The tutorial concludes with a brief mention of further analysis using calculus.

What is the main problem discussed in the video?
