How to determine the absolute and local max min

The video tutorial explains the concepts of absolute and local maximum and minimum points on a graph. It highlights that an absolute maximum is the highest point, while an absolute minimum is the lowest point, but these may not exist if the graph extends indefinitely. The tutorial also covers local maxima and minima, which are points that are the highest or lowest within a specific range. It further explains that there can be multiple local or absolute maxima and minima as long as they occur at the same values.
