the number of bacteria in millions in a petri dish t seconds after an antibiotic is added is given by the function b(t) Assume b(t) is an exponential function first point (1,12) second point (2,2) What is the 1 unit growth factor? what is the 1 unit percent change? How many bacteria in millions are there in the petri dish at the moment the antibiotic is added? Find the function of B(t) How long does it take the number of bacteria to decrease by 50%? include units
