Understanding the Basics of Logarithmic Functions
Before we dive into the specifics of the range of , let's take a step back and understand the basics of logarithmic functions. A logarithmic function is the inverse of an exponential function. In other words, if we have an exponential function of the form , where is a positive real number not equal to 1, then the logarithmic function of the form is its inverse.
The Domain and Range of Logarithmic Functions
The domain of a logarithmic function is all positive real numbers, while the range is all real numbers. This is because the logarithmic function is the inverse of the exponential function, and the exponential function has a range of all positive real numbers.
The Specific Case of
Now, let's focus on the specific case of . This is a logarithmic function with base 8. To find the range of this function, we need to consider the possible values of and how they affect the value of .
The Range of
The range of a logarithmic function is all real numbers. This is because the logarithmic function is the inverse of the exponential function, and the exponential function has a range of all positive real numbers.
However, we need to consider the fact that the base of the logarithmic function is 8, which is a positive real number not equal to 1. This means that the range of is all real numbers, but we need to exclude the value 0.
Why 0 is Excluded from the Range
The value 0 is excluded from the range of because the logarithmic function is undefined when the base is 0. In other words, is undefined.
Conclusion
In conclusion, the range of is all real numbers, but we need to exclude the value 0. This is because the logarithmic function is the inverse of the exponential function, and the exponential function has a range of all positive real numbers.
