Question 511020
A 2.2 billion gain in 29 years would average out to 758 million people per year.


If population growth was linear, the population in 1 AD would have been (6.8*10^9) - 2010(7.58*10^7), roughly -140 billion. Does that make sense?


This is why most linear regressions do not work for predicting extremely small or extremely large x-values.
