Answer
A quantity when experiencing exponential growth, increases exponentially as the growth is non linear meaning that the values change without a constant factor increase in the value.
Work Step by Step
For example y=$2^{x}$
when x=2
y=$2^{2}$ = 4
when x=3
y=$2^{3}$ = 8
when x=4
y=$2^{4}$ = 16
This shows that the values are increasing drastically and experiencing exponential growth as the values are increasing in value.
