Answer:

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

Explanation:

The domain of a real function, or expression, is a set that contains every possible value the independent variable (#x#, in our case) can take, so that the evaluation is possible and makes sense.

#abs(2x-1)# makes sense for any real value of #x#, therefore its domain is all real numbers.
