An antibiotic is introduced into a colony of 12,000 bacteria during a laboratory experiment. The colony is decreasing by 14.9% per minute. Which function can be used to model the number of bacteria in the colony after x minutes?

f(x) = 12000(1 + 14.9)x

f(x) = 12000(1 - 14.9)x

f(x) = 12000(1 + 0.149)x

f(x) = 12000(1 - 0.149)x
