Consider the recursive relation
9xt
X++1 = c
1+ ¤t
where c > 0 is an unknown constant.
(a) Find all equilibrium points.
Answer: x = 0
and x = -1+9*c
Your last answer was interpreted as follows:
Your last answer was interpreted as follows:
-1+9. c
(b) For which values of c is the zero equilibrium stable and the other one unstable?
Answer: c < :
(c) For which values of c is the zero equilibrium unstable and the other one stable?
Answer: c < +
(d) Let us call c* the critical value that distinguishes the two cases above. What is the value of c* ?
Answer: c*
(e) In the case of c = c*, we cannot say anything about the stability since |f'(7)| =
