Aaron compared the counts of two species of bacteria after being treated with an antibiotic. The results are shown in the table below. Time (hours) Bacteria 1 Count Bacteria 2 Count 0 6,000 8,000 1 5,000 6,000 2 4,500 4,500 3 4,000 3,375 4 3,200 2,531 Which statement best describes this situation? A. The counts of both species are changing exponentially. B. Only the count of bacteria 1 is changing exponentially. C. The count of neither of the species is changing exponentially. D. Only the count of bacteria 2 is changing exponentially.
