Concept explainers
Two million E. coil 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
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.)
