Graph shows the vertical asymptote at x nearing 4.

Explanation:

X must be more than 4 otherwise log(x-4) will be invalid;
Let us make a table of x & y
#x rarr rarr log(x-4)#
------- ----------------
#5 rarr rarr 0#
#9 rarr rarr .7#
#14 rarr rarr 1#
#19 rarr rarr 1.18#
#24 rarr rarr 1.30#
Now we can plot the Graph with the value of x and y.On this Graph Vertical asymptote is at x nearing the value 4.
graph{log(x-4) [-20, 20, -10, 10]}
