In this article, we investigate the existence and direction of the Neimark-Sacker bifurcation of the equation in the title with positive parameters and with arbitrary non-negative conditions. First, we study the existence of the Neimark-Sacker bifurcation of the system by analyzing the characteristic equation. Secondly, we investigate the direction and stability of the bifurcating invariant curve by using the normal form theory. Finally, computer simulation is performed to illustrate the analytical results found.
