The domain of the function [tex]y = \sqrt{-x - 3[/tex] is the set of real numbers less than or equal to -3
The function is given as:
[tex]y = \sqrt{-x - 3[/tex]
Set the radicand of the function to greater than or equal to 0
[tex]-x - 3 \ge 0[/tex]
Add 3 to both sides
[tex]-x \ge -3[/tex]
Solve for x
[tex]x \le -3[/tex]
The above means that, the values of x must not exceed 3
