Explanation
Given the function;
[tex]p(t)=2(3)^t[/tex]We are asked to find the population of the bacteria after 7 days.
Given that t represents the number of days, we can find the population by substituting 7 into the formula. This can be seen below.
[tex]\begin{gathered} p(t)=2(3)^7 \\ =2\times2187=4374 \end{gathered}[/tex]Answer: 4374
