The graph of the function f(x)=V x+4 is shown below
The domain of the function is

The function domain is:

{x|x ≥ -4}

Hence, option 4 is correct.

Step-by-step explanation:

Given the expression of the function

We know that the domain of the function is the set of input values for which the function is real and defined

We know that the value inside the radical expression must be greater than or equal to 0 so that the function remains defined.

so

subtract 4 from both sides

simplify

Therefore, the function domain is:

{x|x ≥ -4}

Hence, option 4 is correct.

uhhh idk u yolo?
