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.
