2010 is 10 years after 2000, so the model predicts a population of
6084e^0.12 = 6859.69
That's overestimating by 6.69, or about 0.0976%
I guess you'd need to study some on actual population trends to see whether you expect the model to remain close to the reality.
Since 2000, world population in millions closely fits the exponential function
y=6084e^0.0120x
(everything after the ^ is an exponent)
where x is the number of years since 2000.
Answer the following questions:
1.The world population was about 6853 million (or 6.853 billion) in 2010. How closely does this function approximate this value?
2.Use this model to predict the population in 2020 and 2030. Using complete sentences, do you think this model gives an accurate prediction for 2030? Why or why not.
