Bounded functions

The video tutorial explains the concept of boundedness in mathematical graphs, including bounded above, bounded below, and unbounded graphs. It provides examples using different types of functions: a polynomial, a semicircle, and a rational function. The tutorial aims to help students understand how to identify boundedness in graphs and offers practical examples to illustrate these concepts.

How can you determine if a graph is bounded both above and below?

What are the implications of a graph having no absolute maximum or minimum?
