Answer:
True
Explanation:
Domain is the set of x values for which the function is defined.
The given logarithm function is

Now, we know that logarithm function is defined for those x values which are greater than zero.
Hence, the domain of the given equation is x >0
The base b should be greater than 0 except 1.
Therefore, the given function is not defined for negative values of x and at x =0.
Hence, we can conclude that the domain is the set of all positive real numbers.
The given statement is true.
