What are the values for x in x > -2 when the domain is positive?

The statement: x > -2 says that for any value that it may take, x must 
be greater than -2. But because of the domain restriction (that of 
positive numbers), the answer is slightly different.

The answer to this problem, x > -2 (with the domain being that of 
positive numbers) is the set of numbers 1,2,3,4,5,... because all 
these positive numbers are greater than -2.
