Answer:
All real numbers
Step-by-step explanation:
The domain is the set of x values that we can plug into the function and it will have a y value.
The domain is the "allowed" x values of a function.
Exponential functions of the form [tex]y=a^x[/tex], where a is a constant have domain of "all real numbers".
The function in this problem is of this form with a "-5" at the end, which shifts the function vertically 5 units down. This doesn't affect x values (or domain)
Hence, the domain is the set of all real numbers.
