Question

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

Answer 1

Domain: `x >= -3`

Explanation:

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]
