Given a Cartesian graph of the derivative of a function be able to determine when the function is increasing
and decreasing or has obtained an extrema.
• How can you tell whether the derivative of a function is increasing or decreasing given a function?
• Where is the maximum or minimum of the graph of the derivative of a function?
• What does the inflection point of a graph tell you about the graph of the derivative of the function?
This lesson is almost the opposite of the previous lesson. This time, you will learn how to determine whether the graph of a derivative function is increasing or decreasing during different intervals. This concept is explained very well. A logistic function is shown at the end of this lesson to drive home the idea of how the inflection point relates to the graph of the derivative function.
