Solution
Exponential growth and decay functions are written in the form as shown below:
[tex]F(t)=A_0.b^{kt}[/tex][tex]\begin{gathered} A_0=initial\text{ amount} \\ b=growth\text{ factor} \\ k=growth\text{ rate} \\ t=? \end{gathered}[/tex]From the observation , the value t represents time from the observation
[tex]F(t)=A_0.b^{kt}[/tex]Therefore the value of t =
So the answer is Option D
