The domain is all real numbers, or #RR#.


The domain of a function, is the set containing all possible values the independent variable is "allowed" to take, in order for the function to be well-defined. There is no possible way #abs(3x - 2)# can be undefined for a real #x#, so there are no restrictions on the domain of this real function.

Therefore, the domain is all real numbers.
