Given that the function f (x) is an odd function and the domain of definition is r, when x > = 0, f (x) = - x2-2x, find the expression of F (x) in the domain of definition

Given that the function f (x) is an odd function and the domain of definition is r, when x > = 0, f (x) = - x2-2x, find the expression of F (x) in the domain of definition

Only x is required
