The price of a particular crop per bushel at time t (in months) is approximated by f(t) = 2 + 0.002t + 0.02e-. What is the percentage rate of change of f(t) at t = 0? t = 1? t= 2? The price of the crop is expected to change at a relative rate of |% per month when t = 0. (Do not round until the final answer. Then round to two decimal places as needed.) The price of the crop is expected to change at a relative rate of % per month when t = 1. (Do not round until the final answer. Then round to two decimal places as needed.) The price of the crop is expected to change at a relative rate of |% per month when t = 2. (Do not round until the final answer. Then round to two decimal places as needed.)
