What is an exponential function?

An exponential function f is given by

f(x) = b^{x},

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.

The following diagram compares the graphs of exponential functions. Scroll down the page for more examples and solutions on the graphs of exponential functions.

**Graphs of Exponential Functions**

We often encounter exponential functions in science and mathematics. Exponential functions have a unique set of characteristics and asymptotic behavior that make their graphs recognizable. It is important to be able to recognize the graphs of exponential functions, the graphs of their inverses (logarithmic functions) and to know properties that help us solve equations with exponents and logs.
