Answer:
C)
Step-by-step explanation:
Exponential means that something is growing faster as time goes by.
In C, we can see that at
x=1, f(x) is 2
When x=2, this doubles to 4. (+2)
When x=3, this becomes 8. (+4)
You can see that more is being gained at f(x) while x is only increasing by one. This shows exponential growth.
