domain and range of the function modx-1
Let f(x) = |x - 1|
f(x) is defined for any real number.
So, domain of f is R.
For x being a real number, |x - 1| is greater than or equal to zero.
Or it can be said that |x - 1| is a real number excluding negative real numbers.
So, range of f is R - R- , where R- is the set of negative real numbers.
