For this project you will be creating an exponential growth function to model the world population (f(x) = abx). To do this you will need two points. The first point being the
current world population 7.88 billion people. Go to the internet to find a second point
pick any year in the 1900's, and cite that source (you can use world population. With
two points you can create an exponential function, like we did in class. Let x = the
year, f(x) = world population in billions.
