The Naimark-Sacker bifurcation and symptotic approximation of the invariant curve of a certain difference equation

We compute the direction of the Naimark-Sacker bifurcation for the difference equation (Formula presented.) where p is a positive number and the initial conditions x-1 and x0 are positive numbers. Furthermore, we give the asymptotic approximation of the invariant curve
