(1 point) Consider the following discrete-time dynamical system, which is called the discrete logistic model and which models the size of a population over time: Ntti = Ne 1+ R(1 - 100 Find all equilibria when R = 0.9 and determine their stability. Locally stable equilibria are Unstable equilibria are (Enter the equilibria as a comma-separated list. If there are no equilibria of a given type, enter "none".) Find all equilibria when R = 2.5 and determine their stability. Locally stable equilibria are Unstable equilibria are (Enter the equilibria as a comma-separated list. If there are no equilibria of a given type, enter "none".)
