Already got the second part done just need help with the first part ASAP please!

Von Bertalanffy's equation states that the rate of growth in length of an individual fish is proportional to the difference between the current lennth / and the asymptotic length L? (in centimeters). (a) Write a differential equation that expresses this idea. (Assume L? > L. Use k for the proportionality constant.) dL k(La-L) dt (b) Make a rough sketch of the graph of a solution of a typical initial-value problem for this differential equation. L(t) L(t) La L (0) L(t) La L (0) La L (0) L(t) L (0) La
