Answer 1

$y=\sqrt{x+6}\\\\The\ domain:\\\\x+6\geq0\ \ \ |-6\\\\\boxed{Answer:\ C\ x\geq-6}$

Answer 2

The domain would be the X values that make the expression defined.

Set Y to 0 and solve for X
 
0 = SQRT(x+6)

 Raise both sides by the power of 2

0 = x+6
Subtract from each side:
x = -6

So the domain would be x = > -6

The answer is C
