Answer:
The correct option is 4.
Step-by-step explanation:
The given function is
[tex]f(x)=\ln x[/tex]
ln x represents the natural logarithmic function. The base value of a natural logarithmic function is e. It means
[tex]\ln x=\log_e x[/tex]
Substitute [tex]\ln x=\log_e x[/tex] in the given function.
[tex]f(x)=\log_e x[/tex]
The function [tex]f(x)=\ln x[/tex] and [tex]f(x)=\log_e x[/tex] are equivalent.
Therefore, the correct option is 4.
