Problems $p_{i+1} = p_i + r(1 - p_i)p_i - hp_i$. (1) Problem 1 [3 points]: This model contains three terms: $p_i$, $r(1 - p_i)p_i$, and $hp_i$. Briefly (one sentence each) describe what each of these terms represents in the context of the real- world system we're trying to model. Problem 2 [3 points]: Find all equilibrium points of the model. Be sure to show your work. Problem 3 [14 points]: Analytically determine conditions under which each equilibrium is stable. These conditions should be written in terms of bounds on the parameter $r$. Be sure to show your work.
