How to find the limits of a piecewise function by graphing first

The video tutorial explains how to graph functions and understand restrictions. It covers the concept of left and right hand limits, demonstrating how to evaluate them using graphs. The tutorial also discusses when a general limit does not exist. Finally, it introduces a similar problem involving absolute values and exponentials.
