The video tutorial explains the concept of continuity in mathematics, focusing on how Y values must be equal for functions to be continuous. It discusses the conditions under which functions become discontinuous, particularly at X = -1, and demonstrates how to find the Y value that ensures continuity. The tutorial also covers graphing techniques and understanding slopes, emphasizing the importance of these concepts in mathematical analysis.

What is the primary condition for functions to be continuous?
