Question

how does the average rate of change of the population from 2013 to 2015 compare to that from 2011 to 2013? explain what this means in terms of the population of the country.
from 2011 to 2013, the population actually decreased, while from 2013 to 2015, there was a significant increase. this indicates that the country faced a population decline initially, which was reversed and turned into a positive growth rate after 2013.
from 2011 to 2013, the average rate of population growth was slower than from 2013 to 2015. this suggests that the population growth was stagnating earlier and picked up speed significantly after 2013.
both intervals (2013 to 2015 and 2011 to 2013) have the same average rate of population growth, which is 0.35 million people per year.
from 2013 to 2015, the average rate of population growth was faster than from 2011 to 2013. this means that the population increased more quickly in the latter years, indicating a surge in growth during the 2013 to 2015 period.

Explanation:

The average rate of change (which is a concept in calculus related to how a quantity changes over an interval) for population growth is being compared between two time - intervals. A higher average rate of change from 2013 - 2015 compared to 2011 - 2013 means the population increased more rapidly in the later period.

Answer:

From 2013 to 2015, the average rate of population growth was faster than from 2011 to 2013. This means that the population increased more quickly in the latter years, indicating a surge in growth during the 2013 to 2015 period.
