Answer:
The vertical asymptote of the function f(x) the vertical asymptote of the function f(x) is :
x= -3
Explanation:
The vertical asymptote of the logarithmic function are the possible value of the x where the function tends to infinity.
i.e.

Here we have the function f(x) as:

so when x= -3
we have:

Hence, we get the vertical asymptote is: x= -3
