Domain & Range
Example 3
Find the domain and range of the function:
.
![DREx3-1 DREx3-1](https://claregladwinresd.glk12.org/pluginfile.php/2201/mod_book/chapter/4967/Power/images/DREx3-1.png)
Step 1. Find the domain.
Since the function is not representing a situation, the x can be any real number.
Therefore, the domain is .
Step 2. Find the range.
This graph is shifted down 2 and has an asymptote at y = -2. It also has a negative a-value.
Therefore, the range of the function is .
