Chris Murphy and Alex Murphy, Facebook

Facebook World Domination





Y=.44*1.1x


the y is the number of users for each month and future months
the x is the number of months since facebook was created
constant a (.44) is the initial value of x-the amount of people who were on facebook when it was first created

constant b (1.1) is a positive growth factor of people on facebook; every time it is a 10% increase.


According to the equation there are approximately 616,597,360 users on facebook this month. In six months, there will be approximately 1,090,568,274 users on facebook. By plugging in the number of months from now and in six months from now since the creation of facebook for x, we figured out our y (number of users).

6,793.248608=.44*1.1^x x=101

I found this by dividing both sides by .44, and then finding the log of both sides. I divided the log of (6,793.248608/.44) by the log(1.1) to get 101 months. Therefore in May of 2012 the entire planet will be on facebook.
