What is the max and min of a horizontal line on a closed interval

The video tutorial discusses graph analysis, focusing on understanding maximum and minimum values within closed intervals. It explains the importance of continuity and closed intervals in determining maximums and minimums, using examples to illustrate these concepts. The tutorial emphasizes that a maximum occurs when no value is greater, and a minimum occurs when no value is lower, within the specified interval.

Explain the conditions under which a maximum value does not occur in a function.
