Understanding Limits of Piecewise Functions

The video tutorial explores the concept of limits in piecewise functions, focusing on calculating one-sided and two-sided limits. It begins with an introduction to limits and piecewise functions, followed by detailed examples of calculating limits as X approaches specific values, such as 4, 2, -1, and 0. The tutorial emphasizes understanding the function's behavior from both sides of a point and highlights scenarios where limits do not exist due to differing values from each side.

What is a piecewise function?

• A function defined by a single equation

• A function defined by multiple equations over different intervals

• A function that is always continuous

• A function that has no limits
