Answer:
The correct option is <u>(C) Exponential growth</u>.
Step-by-step explanation:
The simplest exponential function is: f(x) =
, a>0, a≠1
If the x is positive then graph of exponential is increasing and if the x is negative then graph of exponential is decreasing.
In given function 
x is positive so, it is graph of exponential growth.
Hence, the correct option is <u>(C) Exponential growth</u>.
