It depends on where the square root operator has its end.


From your post, I can not determine it.

Don't use the "√" symbol in your posts. We can't tell whether the expression is

sqrt%28x%5E2%2B7%2B5%29 or sqrt%28x%5E2%2B7%29%2B5 or sqrt%28x%5E2%29%2B7%2B5

Evaluating any of those expressions at x=3 does not yield any of the answer choices. Have you shown the expression correctly?

Re-post, making sure you correctly show the correct expression.
