Answer:
x ≥ -4
Step-by-step explanation:
We have to find the domain of definition for the function y=[tex]\sqrt{x+4}[/tex]
It is clear from the above expression of the function that to get the real value of y, (x+4) can not be negative because the square root of any negative term is imaginary i.e. not real.
So, (x+4) ≥ 0
⇒ x ≥ -4
So, x ≥ -4 is the domain of the given function. (Answer)
