How to evaluate the limit to infinity of a rational function

The video tutorial covers the evaluation of limits in calculus, focusing on different methods such as direct substitution and graphing. It explains how to handle undefined limits, identify holes and asymptotes, and evaluate limits at infinity. The tutorial also discusses piecewise functions and how to graph them to understand limits at points of discontinuity.
