The function f(x) = 4(2) ^x represents the number of people who share a cat
video x hours after it first appears on a website. how does the number of
people sharing the video change each hour?

It will double every hour.

Step-by-step 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.
