Question

When Facebook was founded it had three initial users. Now, since so many people use Facebook, they use computers to calculate the total users. At the end of each month, at midnight, the computers determine the number of users by 75% of each month.

Answer 1

They INCREASE by 75% each month

 

75% increase is 100% + 75% = 175% = 1.75

 

The exponential function is F(t) = 3*(1.75)^t for t in months
