Use the equation below to answer questions 13-15: I." = U2 _ '52: b :5 U 13. Which of the felltmiug best describes the steady state values of this equation? A) Our steady state value; are h (stable) and b (unstable). B) Our steady state values are b (unstable) and b (stable). G) Our steady state values are b and t-: both are unstable. D} Our steady state values are l.- and I): both are stable. 14. From the plots belerw1 identify the correct y} vs. 3;. EM IE?! PM (a) (b) (c) (a) 15.
