1. Section 2.3 – The Derivative Function Section 2.3.1 – The Graph of the First Derivative Function

2. This is the graph of f(x). This is the graph of f ‘ (x). How do we get this? f(x) inc f ‘ (x) pos f(x) dec f ‘ (x) neg

3. This is the graph of f(x). This is the graph of f ‘ (x).

4. Steps to Graphing The First Derivative 1. Graph the x-intercepts (slope of tangent is zero) 2. Mark points of inflection (opening up/down changes) 3.Analyze trends of slopes and fill in shapes. Note: the y-axis of the derivative graph is no longer a y-coordinate, but a VALUE OF SLOPE

5. Example of Graphs of First Derivative
