What is the domain of f(x)=-(1)?3O A. y> 0OB. x< 0O C. All real numbersO D. x > 0

The term domain in mathematics is the set of all the possible values of "x" the function can take.
For the given function, f(x) = (1/3)^x, any number can take the value of x. Hence, the domain of the given function is all real numbers. (Option C).
