The quantity grows at a rate directly proportional to its present size The function curve can be derived from a gompertz law of mortality, which states the rate of absolute mortality (decay) falls exponentially with current size For example, when it is 3 times as big as it is now, it will be growing 3 times as fast as it is now

In more technical language, its instantaneous rate of change (that is, the derivative) of a quantity with respect to an independent.
It is also called the exponential growth rate, or the continuous growth rate.
Malthusian growth model a malthusian growth model, sometimes called a simple exponential growth model, is essentially exponential growth based on the idea of the function being proportional to the speed to which the function grows. He applied the same mathematical formula to describe plant size over time The equation for exponential mass growth rate in plant growth analysis is often expressed as M (t) is the final mass of the plant at time (t)
M 0 is the initial mass of the plant Rgr is the relative growth rate Rgr can then be written as: Biological exponential growth is the unrestricted growth of a population of organisms, occurring when resources in its habitat are unlimited
[1] most commonly apparent in species that reproduce quickly and asexually, like bacteria, exponential growth is intuitive from the fact that each organism can divide and produce two copies of itself.
The doubling time is the time it takes for a population to double in size/value It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time When the relative growth rate (not the absolute growth rate) is constant, the quantity undergoes exponential growth and.
