C.Simon is correct because even though the input values are opposite in the reflected function, any real number can be an input.

Step-by-step explanation:

The domain of a function is all the values that can be put into the independant variable in order to value the dependant value, this basically means that the domain is all the values that you can give to the "x", and since you can put any value into the "x"the domain of that function is all the real numbers.
