Can you solve this question?

thx so much

(3) If a function P(t) represents a system that changes over time t then the existence of limt- P(t) (as a finite number) means that the system reaches an equilibrium (or steady state). Let K Poet P(t) = K + Polet - 1) where k and Po are constants. (a) Determine if P(t) reaches an equilibrium. (b) Find the value of the equilibrium of P(t) if an equilibrium exists
