Using an exponential function, it is found that the multiplier that would allow you to predict the population of bacteria after 2 hours is of 9.
<h3>What is an exponential function?</h3>
An exponential function is modeled by:

In which:
In this problem, the bacteria triples every hour, hence the rate of change is b = 3, and the equation is:

Hence, after 2 hours:

Which means that the multiplier is of 9.
