1. The problem statement, all variables and given/known data The difference equations below model the yearly populations of foxes and rabbits, measured in tousands. The foxes kill the rabbits for food. xn = xn-1+0.03xn-1-0.001xn-1yn-1 yn = yn-1-0.02yn-1+0.005xn-1yn-1 1. Which population does x represent and which population does y represent? Give a reason for your answer. 2. Find the fixed points of this model. 3. The attempt at a solution 1. I believe "x" represents the population of rabbits (the prey) and "y" represents fox (predator). I know that xn decreases by 0.001xn-1yn-1 whereas yn increases by 0.005xn-1yn-1. But I don't know how to explain this in a proper way... 2. I appreciate it if someone can show me what needs to be done for this question.
