How to evaluate left and right hand limits of reciprocal function

The video tutorial explains how to evaluate limits as X approaches a specific value, using direct substitution. It discusses the behavior of graphs as they approach infinity and the importance of approaching limits from both sides. The tutorial also covers left and right side limits, highlighting how graphs behave differently when approaching from different directions.

What method can be used to identify the limit as X approaches 3?

What is the significance of approaching the limit from both sides?

What happens to the limit when the graphs approach different values from the left and right?

Explain the concept of left and right side limits in relation to the overall limit.

Describe the behavior of the graph as X approaches negative infinity from the left.
