A population of chipmunks moves into a new region at time t=0 months. At time t (in months), the population size is given by P(t) = 100[1+0.3t+(0.04)t^2].
How long does it take for this population to double its initial size P(0)? Include the units in your answer.
What is the average rate of population change between time t=0 and time t=20? Include the units in your answer.
What is the instantaneous rate of growth of the population when the population size is P=200? Include the units in your answer.
