This final project discusses the stability between predator and prey in the modified Lotka-Volterra. This model uses a modified rational Lotka-Volterra model with one predator and one prey. In this model, there are two nonnegative equilibrium points and stability positive equilibrium in the parameters. Furtheremore, a simulation is given for each case that describes the behavior and stabil…
