Using "^" for powers, you can write as:y = ab^x
or alternatively as:
y = a exp(kx)
where a, b, k are different constants, and exp() is the exponential function (e^x).
Exponential Growth is when the growth rate of a mathematical function is proportional to the function's current value. Exponential growth is when an animal or whatever object increasing at an increasing rate. For example 2, 4, 8, 16, 32, 64 etc. This is exponential growth because it is multiple by a consistent number, or two. The key part is that is it multipled not added which would be lineal growth.
The function ( f(x) = 2x^3 ) is neither exponential growth nor exponential decay; it is a polynomial function. Exponential growth is characterized by functions of the form ( a \cdot b^x ) where ( b > 1 ), while exponential decay involves functions where ( 0 < b < 1 ). In ( f(x) = 2x^3 ), the growth rate is determined by the polynomial term, which increases as ( x ) increases, but does not fit the definition of exponential behavior.
That means that the growth is equal to, or similar to, an exponential function, which can be written (for example) as abx, for constants "a" and "b". One characteristic of exponential growth is that the function increases by the same percentage in the same time period. For example, it increases 5%, or equivalently by a factor of 1.05, every year.
The base of 1 is not used for exponential functions because it does not produce varied growth rates. An exponential function with a base of 1 would result in a constant value (1), regardless of the exponent, failing to demonstrate the characteristic rapid growth or decay associated with true exponential behavior. Therefore, bases greater than 1 (for growth) or between 0 and 1 (for decay) are required to reflect the dynamic nature of exponential functions.
implementation of exponential groth
An exponential growth function actually describes a quantity that increases exponentially over time, with the rate of increase proportional to the current value of the quantity, resulting in rapid growth. The formula for an exponential growth function is y = a * (1 + r)^t, where 'a' is the initial quantity, 'r' is the growth rate, and 't' is time.
There is no such thing. "Exponential growth" implies that there is some function - a variable that depends on another variable (often time).

The growth rate of a population is directly related to the exponential function ekt. The constant k represents the growth rate, with larger values of k indicating faster growth and smaller values indicating slower growth. The function ekt models exponential growth, where the population increases rapidly over time.
Reverend Thomas Malthus developed the concept of Exponential Growth (another name for this is Malthusian growth model.) However the mathematical Exponent function was already know, but not applied to population growth and growth constraints. Exponential Decay is a natural extension of Exponential Growth

That would be an exponential decay curve or negative growth curve.
False
y=a*b^x where b>1 and a>1
An exponential function is a nonlinear function in the form y=ab^x, where a isn't equal to zero. In a table, consecutive output values have a common ratio. a is the y-intercept of the exponential function and b is the rate of growth/decay.
A __________ function takes the exponential function's output and returns the exponential function's input.
Yes.
