Question

How do you find the x values at which `f(x)=x^2-2x+1` is not continuous, which of the discontinuities are removable?

Answer 1

`f(x)` is a polynomial and as such it is continuous for any `x in RR`

Answer 2

`f(x)` is a real valued polynomial and is continuous over all `x in RR`. There are no discontinuities.
