Evaluating the limit of a continuous function

The video tutorial explains the concept of limits, focusing on the function X + 1 as X approaches 5. It uses graphical analysis to demonstrate how the function value approaches 6. The tutorial highlights the importance of continuity for direct substitution to work and introduces piecewise functions, emphasizing that direct substitution is only applicable when the function is continuous.

What is the value of the function F(X) as X approaches 5?

Explain how the graph of the function F(X) = X + 1 behaves as X approaches 5.

What is a piecewise function and how does it relate to continuity?

What does it mean for a function to be continuous?

Describe the process of direct substitution in evaluating limits.
