D) {x|x is any real number}
could someone please assist me with this I have no clue
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
exists only for non-negative values of the variable
(I think that is what you meant) is negative when .
In those cases, you can calculate but does not exist.
For all other values of x (when ) exists.
The domain for is all the x such that so the answer is
.
