The document discusses the average value of a function over a closed interval from x=a to x=b. It defines the average value as the integral from a to b of f(x) dx divided by the length of the interval b-a. It also mentions an animated discussion on the average value of a function from the website Visual Calculus and includes a link to more information on the topic.
