It is known that the piecewise function f (x) is an odd function on R. when x > 0, f (x) = x2-2x + 3, the analytic expression of F (x) is obtained

It is known that the piecewise function f (x) is an odd function on R. when x > 0, f (x) = x2-2x + 3, the analytic expression of F (x) is obtained

Let - x > 0, then x < 0, f (- x) = x2 + 2x + 3, f (- x) = - f (x), f (x) = - x2-2x-3, f (x) = x2 − 2x + 3, (x > 0) 0, (x = 0) − x2 − 2x − 3, (x < 0)
