EXAMPLE 3 = Predicting the Size of a Population The initial bacterium count in a culture is 500. A biologist later makes a sample count of bacteria in the culture and finds that the relative rate of growth is 40% per hour. (a) Find a function that models the number of bacteria after t hours. (b) What is the estimated count after 10 hours? (c) After how many hours will the bacteria count reach 80,000? (d) Sketch a graph of the function n(t).
