How to evualte the limit of the piecewise function

The video tutorial covers evaluating limits using algebraic definitions, exploring continuity, and understanding graphical representations of functions. It explains how to reflect graphs about the X and Y axes and discusses constraints leading to jump discontinuities. The tutorial provides a visual understanding of these concepts, helping students grasp the nature of limits and continuity in mathematical functions.

Describe the effect of a negative sign on the outside of a function's graph.

What is a jump discontinuity and how can it be visually identified?
