Question

What is the definition of exponential growth

Answer 1

Exponential Growth
noun;

Growth whose rate becomes even more rapid in proportion to growing total number or size.

Answer 2

Exponential growth is growth that increases by a constant proportion.

Here the rate of change is proportional to the function's current value. In simpler terms we can say that when growth becomes more rapid with respect to the growing total number, then it is called exponential.

For example, the growth of bacteria is exponential.
