Concept explainers
Trace or copy the graph of the given function .f. (Assume that the axes have equal scales.) Then use the method of Example 1 to sketch the graph of f' below it.
Example 1

To sketch: The graph of
Explanation of Solution
From the given graph, it is observed that the graph of f contains the horizontal tangents at two points. Let the two points be A and B.
Note that, the value of the derivative will be zero at the point where the function has the horizontal tangent.
Thus, the graph of
From the point A to left, the graph has strictly negative slope which implies that the derivative graph
From the point B to right, the graph has strictly positive slope which implies that the derivative graph
Graph:
Use the above information and trace the graph of
Thus,
