Answer:
The graph in the attached figure
see the explanation
Step-by-step explanation:
we have
![y=\sqrt{-x-3}](https://tex.z-dn.net/?f=y%3D%5Csqrt%7B-x-3%7D)
we know that
The radicand must be greater than or equal to zero
so
![(-x-3)\geq 0](https://tex.z-dn.net/?f=%28-x-3%29%5Cgeq%200)
solve for x
Adds 3 both sides
![-x\geq 0+3](https://tex.z-dn.net/?f=-x%5Cgeq%200%2B3)
![-x\geq 3](https://tex.z-dn.net/?f=-x%5Cgeq%203)
Multiply by -1 both sides
Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
![x\leq -3](https://tex.z-dn.net/?f=x%5Cleq%20-3)
so
The domain of the function is the interval (-∞,-3]
For x=-3 ---> the value of y=0
The range is the interval {0,∞)
therefore
The graph in the attached figure
