A small lake is stocked with a certain species of fish. The fish population is modeled by the function 15 P = 1+ 7e-0.5t where P is the number of fish in thousands and t is measured in years since the lake was stocked. (a) Find the fish population after 4 years. (b) After how many years will the fish population reach 5000 fish?
