Left hand Limit of a rational function at a hole

The video tutorial discusses the concept of limits, focusing on approaching a point from the left. It covers factoring trinomials to better understand functions, identifying holes and asymptotes in graphs, and analyzing graph behavior near asymptotes. The tutorial concludes with calculating limits using direct substitution, emphasizing the importance of simplifying expressions before applying substitution.
