Transcribed Image Text:3. (a) Find the nonnegative equilibria of a population governed by 32 Xn+1 = x + 2 and check for stability.
(b) Suppose a fraction a is removed from the population in each genera-
tion, so that the model becomes
Xn+1 =
- axn
x2 + 2
For what values of a is there a stable equilibrium only at x = 0?
