Domain: $x >= -4 or x| [-4,oo)$
Range: $g(x) >=0 or g(x)| [0,oo)$

$g(x)=3sqrt(x+4)$ . For domain , under root is undefined for

any negative value. $:. x+4 >=0 or x >= -4$

Domain: $x >= -4 or x| [-4,oo)$

Range has no negative value , Range: $g(x) >=0 or g(x)| [0,oo)$

graph{3*(x+4)^0.5 [-40, 40, -20, 20]} [Ans]

How do you find the domain and range of g(x)=3 sqrt(x+4)g(x)=3 sqrt(x+4)?
