A population of mosquitoes is growing in a pond. Suppose that the initial population (at day ) is 420 mosquitoes and the population doubles in size every 3 days. Assume that the mosquito population grows exponentially. a. Write a function to model the number of mosquitoes in the pond. b. How many mosquitoes will be in the pond after 20 days? Show algebraic work to support your answer. c. When are there 10,000 mosquitoes? Show algebraic work to support your answer.
