Answer: [A]: The domain is:
_________________________________
{x | 1 ≤ x < 5} .
________________________________________
Note: The answer choices given for "A" and "B" are the same; you meant to type:
_________________________
[A]: {x | 1 ≤ x < 5} ;
_________________________
[B]: {x | 1 < x < 5} ;
__________________________
I know this from the answer choices given in the "image/figure" you have attached. Since: " {x | 1 ≤ x < 5} "
__________________________________________
is the correct answer, I just need to remind you to be sure to know that the
" ≤ " is the appropriate sign.
