See below.

Explanation:

f(x) =3ln(x-2)

f(x) is the standard graph of lnx transformed ("shifted") +2 units on the x-axis and scaled by 3 units. These transformations can be seen by the grapgs below.

Graph 1; y=lnx

graph{lnx [-10, 10, -5, 5]}

Graph 2: y=ln(x-2)

graph{ln(x-2) [-10, 10, -5, 5]}

Graph 3: f(x)=3ln(x-2)

graph{3ln(x-2) [-18.02, 18.02, -9, 9.02]}
