Evaluate the limit of the reciprocal function by looking at the graph

The video tutorial covers the process of drug substitution and the challenges faced when the denominator becomes zero. It then explores the difficulties in factoring the problem and the concept of asymptotes, particularly at X equals negative 4. The lesson concludes with a discussion on limits, emphasizing that the left and right hand limits must be the same, and if not, the limit does not exist.
