find range of f(x)= Ix-1I

Open in App

Solution

$Given f (x) = |x - 1| So as we know that the range of modulus function |x| is set of all real values R . Because it is defined for all the values of x and here |x - 1| is nothing but, |x| shifted one unit right on the x - axis so it will also be defined for all the values of x so range will be set of real values R or x \in R .$
