Evaluate the left hand limit of a rational function

The video tutorial covers the concept of limits, starting with an introduction and addressing initial errors. It discusses evaluating limits by plugging in values and highlights the importance of simplifying expressions. The tutorial also delves into graph analysis, focusing on recognizing asymptotes and understanding the behavior of functions as they approach infinity. Finally, it concludes with factoring expressions and summarizing key points.
