Learn how to evaluate the limit of a piecewise function

The video tutorial explains the concept of continuity in graphs and how to evaluate limits. It emphasizes the importance of ensuring that the left-hand and right-hand limits are equal for a limit to exist. The tutorial also covers the use of direct substitution to evaluate limits when dealing with continuous functions, providing a step-by-step example to illustrate the process.

How can you determine if two functions are continuous at a specific point?

Describe the relationship between the left hand limit and the right hand limit for a limit to exist.
