Answer:
The correct option is 2.
Step-by-step explanation:
The given function is
[tex]y=log5x[/tex]
It is an logarithmic function. If a logarithmic function is defined as
[tex]f(x)=log_a(bx)[/tex]
Where, a is base of log and b>0 is constant.
Then, the domain of the function is all real numbers greater than 0, because the logarithmic function is not defined for any negative number.
Since the given function is a logarithmic function, therefore the domain of the function is all real numbers not equal to 0.
[tex]Domain=\{x|x>0\}[/tex]
Therefore option 2 is correct.
