You can put this solution on YOUR website! The domain is all values that x can take on. The only problem I have with this function is that I cannot have a negative inside the square root. So I'll set the insides greater-than-or-equal-to zero, and solve. The result will be my domain:
4 - x ≥ 0
- x ≥ 0 - 4
-x ≥ -4
x ≤ -4/-1
x ≤ 4
The values for x must be less than or equal to 4. Anything else will make the square root function undefined.
