Study Notes

Exponential Functions

Exponential functions have a general shape of a graph that is asymptotic to the x-axis.
The equation representing an exponential function is f(x) = a^x, where a is a constant.
Exponential growth and decay are correctly described as a rapid increase or decrease in a quantity over time.
The mathematical expression for exponential growth of a colony after t hours is N(t) = N0 * a^t, where N0 is the initial population and a is the growth rate.
An example of an exponential function is f(x) = 2^x.
A fundamental polynomial function is not an exponential function, and has a different equation representation.
