A certain population of bacteria has an initial population of 225. the bacteria triples every hour. determine the multiplier tha
dimaraw [331]

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:

y = ab^x

In which:

  • a is the initial value.
  • b is the growth rate.

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

y = a(3)^x

Hence, after 2 hours:

y = a(3)^2 = 9a

Which means that the multiplier is of 9.
