Suppose that a population of bacteria triples every hour and starts with 400 bacteria. Find an expression for the number n of bacteria after time t hours. n(t) = Use it to estimate the rate of growth of the bacterial population at 3.5 hours. (Round your answer to the nearest whole number.) n'(3.5) = bacteria/hr
