Answer:
8000
Step-by-step explanation:
The function is given as:
[TeX] P(n)=i \cdot 2^n [/TeX]
Where I=Initial Population
n=Number of Generations
If [TeX] i=10^3 [/TeX], we want to determine the population of bacteria when n=3.
[TeX] P(3)=10^{3} \cdot 2^3 [/TeX]
[TeX] =(10*2)^3 =20^3 [/TeX]
=8000
There will be 8000 bacteria after 3 generations.
