How to find the limit of continuous functions

The video tutorial explains how to identify continuous functions and evaluate their limits by direct substitution. It demonstrates the process using examples where values are plugged into functions to find limits as X approaches specific numbers. The tutorial also emphasizes the importance of using parentheses during calculations and suggests graphing the functions for visual understanding. The session concludes with an invitation for questions on direct substitution and limits.
