The following diagrams show the exponential growth and exponential decay graphs. Scroll down the page for more examples and solutions on how to graph exponential functions.
Graph Exponential Functions
An exponential function f is given by
f(x) = bx
where x is any real number, b > 0, and b ≠ 1. The number b is called the base.
If b > 1, f(x) is a positive, increasing continuous function. In this case, f(x) is called an exponential growth function.
If 0 < b < 1, f(x) is a positive, decreasing, continuous function. In this case, f(x) is called an exponential decay function.
Exponential Functions and their Graphs
There are certain functions, such as exponential functions, that have many applications to the real world and have useful inverse functions. Graphing exponential functions is used frequently, we often hear of situations that have exponential growth or exponential decay. The inverses of exponential functions are logarithmic functions. The graphs of exponential functions are used to analyze and interpret data.
