Answer:

It will double every hour.

Explanation:

f(x) = 4(2)^x

This is an exponential function so the number of people will increase at a faster rate each hour. It will accelerate.

Lets try entering a few values:

After 1 hour, people = 4*2 = 8

After 2 hours , people =4*2^2 = 16

After 3 hours, people = 4(2)^3 = 32

After 4 hours, people = 4(2)^4 = 64.

It is doubling every hour.
