Let $f(x)=x^2-2x+1.$ For some constant $k, f(x+k) = x^2+2x+1$ for all real numbers $x.$ Determine the value of $k.$
1. Given the function \( f(x) = x^2 - 2x + 1 \), we can rewrite it in a factored form: \[ f(x) = (x-1)^2 \] 2. We are given that for some constant \( k \), the function \( f(x+k) \) is equal to \( x^2 + 2x + 1 \) for all real numbers \( x \). Therefore, we need to find \( k \) such that: \[ f(x+k) = x^2...
