Determine the intervals that a graph is increasing and decreasing

The video tutorial explains how to analyze graphs by identifying increasing and decreasing intervals. It covers the use of interval notation to denote included and excluded values, emphasizing the importance of parentheses. The tutorial also discusses local and relative minima and maxima, explaining how to identify these points within given intervals. The concept of absolute extrema is addressed, noting that they do not exist for graphs extending infinitely.
