In general, an equation of the form $\"image\"$ , where a ≠ 0, b > 0, and b ≠ 1, is called an exponential function with base b.

The standard form of an exponential function is $\"image\"$ .

For $\"image\"$ , the function is defined for all real values of x. Therefore, the domain is $\"image\"$ .

The range of $\"image\"$ is dependent on the sign of a.

To find the range of $\"image\"$ , start with $\"image\"$ , since the definition of exponential function.

The function is $\"\"$ .

Compare the equation $\"\"$ with standard form of an exponential function is $\"\"$ .

The domain of $\"\"$ is $\"image\"$ .
