The domain of the difference of f and g is the set of all x values for which both f(x) and g(x) are defined. Looking at the given functions, we see that both f and g are defined for all x in the real numbers, since there are no restrictions on x in the given expressions.

So, the domain of the difference of f and g is simply the intersection of the domains of f and g, which is the set of all real numbers.

Choice C is the only option that includes all real numbers in the domain, so it is the best choice.
