When given an exponential function that is proportional to itself then its form is the following:
[tex]G(t)=G_0e^{kt}[/tex]
Where:
[tex]\begin{gathered} G_0=\text{ initial value of ''G''} \\ k=\text{ constant of proportionality} \end{gathered}[/tex]
The proportionality constant is equal to the growth factor. Therefore, the growth factor is 0.6.
Since the growth factor is between 0 and 1 this means that the function exhibits exponential decay.
