Respuesta :
Assuming all of "x-3" is under the square root, then the answer is [tex]x -3 \ge 0[/tex] which can be written as x - 3 >= 0 which looks like it points to choice B as the answer
The goal is to figure out which x values will make "x-3" nonnegative (not negative). Taking the square root of a negative number leads to a non-real result. So it's a common thing to make the radicand (stuff under the square root) positive or 0.
