Textbook Problem

Make a careful sketch of the graph if .*f* and below it sketch the graph of *f'* in the same manner as in Exercises 4-11. Can you guess a formula for *f'*(*x*) from its graph?

*f*(*x*) = In *x*

To determine

**To Sketch:** The graph of

Explanation

The given function is

From the graph of

Thus, the derivative of the graph is always positive.

Draw the tangent to the graph at

Recall the fact that, the slope of the function at the point

Therefore,

Thus, the graph of the function
