It is known that f (x) is an odd function defined on R. when x > 0, f (x) = x ^ 2-2x + 1, then the expression of F (x) is Its function-

It is known that f (x) is an odd function defined on R. when x > 0, f (x) = x ^ 2-2x + 1, then the expression of F (x) is Its function-

If x0, then f (- x) = (- x) ^ 2-2 (- x) + 1 = x ^ 2 + 2x + 1 - f (x) = x ^ 2 + 2x + 1, f (x) = - x ^ 2-2x-1
When x > 0, f (x) = x ^ 2-2x + 1
So f (x) = x ^ 2-2x + 1 (x > 0)
=0(x=0)
=-x^2-2x-1(x
