Final answer:
The domain of sqrt(x+4) is all real numbers greater than or equal to -4.
Step-by-step explanation:
To find the domain of √x+4, we need to determine the values of x that allow the expression √x+4 to be defined. Since the square root function is only defined for non-negative values, we set the expression inside the square root greater than or equal to zero:
x+4 ≥ 0
Subtracting 4 from both sides gives us:
x ≥ -4
Therefore, the domain of √x+4 is all real numbers greater than or equal to -4.
