33. An equation that is frequently used to model the population growth of cancer cells in a tumor is th Gompertz equation dy dt = ryln(K/y), where r and K are positive constants. (a) Sketch the graph of f(y) versus y, find the critical points, and determine whether each is asymptotically stable or unstable. (b) For each y in 0 ≤ y ≤ K, show that dy/dt, as given by the Gompertz equation, is never less than dy/dt, as given by the logistic equation,
