More practice with exponential growth

Exponential Growth:

Nt = N0 * 2g

Nt = N0 * e(mt)

m = ln(2)/doubling time

Here's another dataset so you can practice the whole thing on your own:

time popn
0 hr 5.0 * 106
1 hr 8.3 * 106
2 hr 13 * 106
3 hr 22 * 106
4 hr 35 * 106
5 hr 55 * 106
6 hr 87 * 106
7 hr 142 * 106

 


More judging exponential growth...

If you just look at the first part of the actual population data over time, it is hard to tell whether or not it is exponential. In this early growth stage, the graph appears to increase like an exponential graph.
