The given real function is,
f( x )=| x−1 |
The expression | x−1 | is defined for,
Domain of f=R
Also, for x∈R , | x−1 | consider all real numbers.
Hence, the range of f is a set of all non-negative real numbers.
Find the domain and the range of the real function f defined by f (x) = |x – 1|.
Find the domain and range of the real function f defined by f(x)=√x−1.
