Answer:
5 years
Step-by-step explanation:
If the population of penguins is given by the function:

Initial Size =
Triple its Initial Size, P(t)=
Therefore:

It therefore takes 5 years for the penguin population to triple in size.
It would be 3840. The pattern is: x2, x4, x6, x8, x10. Hope that helps! :) :D
