Multiple choice A certain population of bacteria doubles every 60 minutes. Beginning with 50 bacteria in thr culture, the population can be represented by the function A= 50(2)^t, where A is the number of bacteria after t numbers of hours. Which of these is the appropriate domain for the function A in the terms given context?
