F(x y)=xy-x^2-y^2-2x-2y 4

F(x y)=xy-x^2-y^2-2x-2y 4-F (xy)f (x) = f (y) 2xy If we divide both sides by y, and take the limit of both sides, as y approaches 0, we get f' (x)= 2x (limit as y→0) f (y)/y Since f (0) is 0 from the initial conditions (put x=y=0 in the original expression), we have a 0/0Free equations calculator solve linear, quadratic, polynomial, radical, exponential and logarithmic equations with all the steps Type in any equation to get the solution, steps and graph
