Domain: $x >= -3$

Domain (possible value of x): $x+3>=0 or x >= -3$ since under root can not be negative number.

Range (possible value of f(x)): $f(x) >= 0 -1 or f(x) >= -1$

Domain: $x >= -3$ , Range: $f(x) >= -1$ graph{3(x+3)^0.5 -1 [-20, 20, -10, 10]} [Ans]

What is the domain of f(x)=3sqrt(x+3)-1f(x)=3sqrt(x+3)-1?
