Answer: A is the correct answer .
Start with the last two choices .
You have x+ 5 and × - 5 in the square root .
A square root can never be negative .
That means that the lowest value of y can have in the last two choices is 0 .
Now range doesn't include -4.
Now look at choice B .
sqrt (x) is at least 0.
Then you add 5 .
The range doesn't include -4.
Now look at choice A .
sqrt (x) is at lest 0 .
Now ,you subract 5 .
The lowest value y can have is -5 . That includes -4.
Choice A is the answer .
y will be at least 5
Hope it works out !
