Question

This question is confusing me because of the way it is written. We have not learned how to take a derivative yet and are expected to use the definition of a derivative (with limits and whatnot): The population, P, of China, in billions, can be approximated by the function P = 1.267(1.007)^t, where t is the number of years since the start of 2000. According to this model, how fast is the population growing at the start of 2000 and at the start of 2002? Give your answers in millions of people per year. (Note: Use h = 0.01 in your calculations. Round your answers to two decimal places.)

Answer 1

Really confusing 'COMMERCE"

Answer 2

Agreed. I have thus far put in an answer which was marked as wrong, and it goes as follows:
The limit as x approaches 0 of: (P(.01+X)+P(.01)/(.01))=290243742.5

What am I doing wrong? Am I nuts here?
