Solutions

Chapter 2.7, Problem 11E
To determine

To Sketch: The graph of f below the graph of f.

Expert Solution

Explanation of Solution

From the given graph, it is observed that the graph of f contains the vertical tangent at one point. Let this point be O.

At the point O, the derivative of f is infinity and the derivative curve has a vertical asymptote at that point.

From the given graph, it is observed that f has a positive slope.

This implies that, the derivative will be positive everywhere.

From the point A to left, the slope of the graph is decreasing gradually which implies that, the derivative graph must be decreasing towards zero.

From the point B towards right, the slope of the graph is decreasing gradually which implies that, the derivative graph must be decreasing towards zero.

Graph:

Use the above information and trace the graph of f(x) as shown below in Figure 1.

Thus, f is the required graph.
