You can put this solution on YOUR website! Find the domain and range of each function. Show me step by step please.
y=-sqrt(x+3)-1
----
Domain:
x+3 cannot be negative.
---
Solve: x+3>=0
x >= -3
That is the Domain.
===========================
Range:
sqrt(x+3) is always >= zero
--
So, -sqrt(x+3) is always <= 0
---
Therefore y <= -1
That is the Range.

Graph:
