Given no other restrictions, what are the domain and range of the following function? f (x) = x2 - 2x + 1

x^2 - 2x + 1

(x - 1) (x - 1)

X = 1

Given no restriction the domain of the given function f (x) = x^2 - 2x + 1

Is all real numbers

And its range is all non negative real numbers. This is because the function will always results to positive number
