**3. Analysis for Chaotic Behavior of the System**

In order to analyze the behavior of the dynamical system (6), we need to find all its equilibrium points. Note that Figure 6 illustrates how the three-segment piecewise function *g*(*x*) depends on the range of *x*. The investigation of equilibrium points is thus divided into three cases in Sections 3.1–3.3. We then prove that each equilibrium point is of type saddle focus in Section 3.4. In Section 3.5, we describe how to find an initial point to localize a hidden attractor of the system.
