The number of liver transplants performed in a particular country in year x is approximated by f(x) = -233.2 +2337 In x where x 5 and x = 5 corresponds to the year 1995. a) Estimate the number of transplants in 2018. b) Find f'(28). a) According to this model, there should be approximately 1 liver transplants in 2018. (Round to the nearest integer as needed.) b) f'(28)= 1 per year (Round to the nearest integer as needed.)
