Two million E . co li bacteria are present in a laboratory culture. An antibacterial agent is introduced and the population of bacteria P t decreases by half every 6 hr. The population can be represented by P t = 2 , 000 , 000 1 2 t / 6 . a. Convert this to an exponential function using base e . b. Verify that the original function and the result from part (a) yield the same result for P 0 , P 6 , P 12 , and P 60 . (Note: There may be round-off error.)
