Exponential Models – Updated

I posted last week with my model for Arawaks on Hispaniola — using exponential decay to model native populations after Columbus arrived and link to some US History content. I sat down with our US History teacher and put together two more graphs with different data sets — we now have Arawaks on Hispaniola (1491 – 1650), native populations in Mesoamerica (1518 – 1623) and the US Census (1790 – 2010). Also refined the model and added to the table to make them a bit easier to use and facilitate further analysis. They’re three pretty interesting, but also different, data sets that I think are set up well to analyze a number of properties of exponential functions. Graphs look like this:

Three graphs are here:
