Answer:

Explanation:

The domain of a function is the set of all possible input values (x-values) for which the function is defined. In the case of the function:

y = √(x + 4)

The square root of a real number is defined for non-negative values. Therefore, for this function, the expression inside the square root, x + 4, must be greater than or equal to 0 to avoid taking the square root of a negative number. So, you have:

x + 4 ≥ 0

To find the domain, solve for x:

x ≥ -4

The domain of the function is all real numbers greater than or equal to -4, expressed in interval notation as:

Domain: [ -4, ∞)
