Suppose,y=f(x)=-4+sqrt(x+3)

*Here,
f(x)=-4+sqrt(x+3)
If we substitute the value of x less than-3,the value of equation will be indefinable. *

So,DomainRR={x:x inRR,x>=(-3)}

Again, for the value of domain set, the value of range set will be greater than or equal -4

So,RangeRR={y:y inRR,y>=(-4)}color(brown)((Ans.))
