Answer:
Option d) all real numbers
Step-by-step explanation:
we have
[tex]y=\log8^x[/tex]
using a graphing tool
The graph of the equation is a line that represent a direct variation ( the line passes through the origin)
therefore
The domain is all real numbers ---->interval (-∞,∞)
The range is all real numbers ---->interval (-∞,∞)
see the attached figure to better understand the problem
