Question

What is the domain of the function y=sq root x+4

Answer 1

x ≥ -4

Explanation:

We have to find the domain of definition for the function y=
`√(x+4)`

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)
