1. In a tiny country, the current population is 200,000 and is increasing at 2.5% per year. Is this situation describing a linear or exponential increase? Write several sentences to convince me of your answer. b. Write a function describing this situation, and sketch its graph. (Hint: It might help to start by making a table) c. The country can produce enough rice for 300,000 people. Assuming they continue to produce the same amount of rice each year, how long will it be before there are shortages in rice and they have to start importing it? 2.
