Master How to determine the boundness of a function

The video tutorial explains how to determine if a function is bounded, bounded above, bounded below, or not bounded. It introduces the concept of boundaries in graphs and provides examples using different types of functions: square root, reciprocal, trigonometric, and piecewise. Each example illustrates whether the function is bounded or not, and in which direction. The tutorial concludes with a summary of how to assess the boundedness of a function.
