Answer:
The value of
as x approaches +∞ is:
f(x) → ∞
Explanation:
We are given a logarithmic function f(x) as:

We know that the logarithmic function
is defined for x>0 and the graph of the function increases continuously and goes or tends to infinity as x tends to infinity.
Hence, here also if x → ∞
then f(x) → ∞
Also it could be seen with the help of the graph of the function f(x)
