How to navigate the boundaries of piecewise functions
In short: Mastering limits requires more than just plugging in numbers. This video demonstrates how to identify and use the correct function definitions when approaching specific values in piecewise-defined functions.
In this AP Calculus AB lesson, instructor Bill Scott explains the essential process of evaluating limits for piecewise functions. The core challenge lies in ensuring you apply the appropriate part of the function's definition based on which side of the boundary the x-value approaches.
The lesson is part of the Khan Academy AP curriculum, developed with input from educators like Scott, who teaches at Phillips Academy in Andover, Massachusetts.
