Extrema of functions

The video tutorial explains the concepts of absolute and relative extrema in functions, using graph analysis to identify these points. It covers how to determine whether a graph has absolute or relative maxima and minima, and discusses the behavior of graphs at endpoints. The tutorial provides examples to illustrate these concepts, emphasizing the importance of understanding the context and questions being asked when analyzing graphs.

What are the absolute maximum and minimum values of a function?

Describe how to identify the extrema of a function using graphing technology.

What does it mean for a graph to have no absolute maximum or minimum?

Explain the difference between absolute and relative extrema.

How can you determine the relative maximum and minimum values on a given interval?

How can you express the location of a relative maximum or minimum?

What is the significance of endpoints in determining absolute extrema?
