Interest is often modeled as an exponential function because it grows at a rate proportional to its current value. In compound interest, for example, the interest earned in each period is added to the principal, leading to interest being calculated on an increasingly larger amount over time. This results in a rapid increase where the growth accelerates, characteristic of exponential growth. As a result, the formula for compound interest, ( A = P(1 + r/n)^{nt} ), reflects this relationship, showing how the amount grows exponentially based on the interest rate and time.
Yes. Anything that multiplies repeatedly like that is exponential, also sometimes referred to as geometric.

Exponential relationship!
fundamental difference between a polynomial function and an exponential function?
No, a linear function does not increase faster than an exponential function. While linear functions grow at a constant rate, exponential functions grow at an increasing rate, meaning that as the input value increases, the output of the exponential function will eventually surpass that of the linear function. For sufficiently large values of the input, the exponential function will outpace the linear function significantly.
Compound interest.
A __________ function takes the exponential function's output and returns the exponential function's input.
Yes. Anything that multiplies repeatedly like that is exponential, also sometimes referred to as geometric.
The parent function of the exponential function is ax
No. The inverse of an exponential function is a logarithmic function.

If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.
If y is an exponential function of x then x is a logarithmic function of y - so to change from an exponential function to a logarithmic function, change the subject of the function from one variable to the other.
fundamental difference between a polynomial function and an exponential function?
No, an function only contains a certain amount of vertices; leaving a logarithmic function to NOT be the inverse of an exponential function.
