It is known that f (x) is an odd function defined on R. when x ≥ 0, f (x) = x2-2x, then the expression of F (x) on R is () A. y=x(x-2)B. y=x(|x|-1)C. y=|x|(x-2)D. y=x(|x|-2)

It is known that f (x) is an odd function defined on R. when x ≥ 0, f (x) = x2-2x, then the expression of F (x) on R is () A. y=x(x-2)B. y=x(|x|-1)C. y=|x|(x-2)D. y=x(|x|-2)

When x < 0, - x > 0, ∵ when x ≥ 0, f (x) = x2-2x, ∵ f (- x) = x2 + 2x, ∵ f (x) is an odd function defined on R, ∵ f (- x) = x2 + 2x = - f (x), ∵ f (x) = x2-2x = - x (x + 2) = x (- X-2), (x < 0), ∵ y = f (x) = x (| x | - 2), so select D
