A scientist counts 60 bacteria present in a culture and finds that the number of bacteria quadruples each hour. Which of the following analytical models illustrates thissituation?

Let:
a = initial number of bacteria
x = number of hours
b = growth constant
so, the model which illustrates this situation is an exponential function of the form:
[tex]\begin{gathered} a\cdot b^x \\ where \\ a=60 \\ b=4 \\ so\colon \\ 60\cdot(4)^x \end{gathered}[/tex]
