The paper considers the problem of finding the range of the functional I = J(f(z(0))<(f(z(0))over bar)>,F(zeta(0)),<(F(zeta(0))over bar)> defined on the class m of functions paris (f(z),F(zeta)) that are univalent in the system of the disk and the interior of the disk, using the method of internal variation. We establish that the range of this functional is bounded by the curve whose equation is written in terms of elliptic integrals, dependmg on the parameters of the functional I.
