See the explanantion

#### Explanation:

To find the x-intercept mathematically

If

Another way of writing this is:

The x-intercept is when

So the x-intercept is at

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You asked 'how' would you graph ....

The method would be to build a table of values.

The top row would have the values of x

The next row down would have the values of ln(x)

and the row below that would have the values of

This last row gives the values for

You would then mark a series of points that maches both your value of

Your graph should look something like this:
