4.3) Consider the following function. (If an answer does not exist, enter DNE.) f(x) = ln(4 − ln(x)) (a) Find the vertical asymptote(s). (Enter your answers as a comma-separated list.) x =

Using it's concept, it is found that the vertical asymptotes of the function are:

A vertical asymptote of a function f(x) are the values of x for which the function is outside it's domain.

For the ln function, that is, , they are the values of x for which:

In this problem, the function is:

For the inner function, x = 0 is a vertical asymptote, as is outside the domain.

For the outer function:

Step-by-step explanation:

Given function:

Since,

Here, if

Hence, the vertical asymptotes of f(x) are:

.
