Step 1:

The function is

Use the natural logarithmic function :.

The function is defined only if , therefore the domain of the function is .

The domain of the function is .

Step 2:

To find the -intercept ,

Substitute in function

The -intercept  is at .

Step 3:

The graph of the basic log function moves the positive side of the -axis to reach the -axis , with the line never going to the left of the limitation that must be greater than zero.

Therefore, Vertical asymptote is

Vertical asymptote is

Graph:

Solution :

The domain of the function is .

The -intercept  is at .

Vertical asymptote is
