x? = x(0.04 ? 0.0008x ? 0.004y) , y? = y (0.1? 0.005x ? 0.002y)
Let x and y represent the populations (in thousands) of two species that share a habitat. For each system of equations, find and assess the stability of the equilibrium points. Remember that, for real populations, both x0 and y0 must be nonnegative for ( x0, y0) to be an equilibrium point.
