Find derivat O A. The growth rate tells the average growth from time t = 0 and t = 20. B. The growth rate tells the difference between the rate of growth at the beginning of t = 0 and t = 20 Find derivat OC. The growth rate tells the rate at which the population is growing at time t = 20 - 1. OD. The growth rate tells the rate at which the population is growing at time t = 20.
