Final answer:
The domain of the function y = sqrt(x + 4) is all real numbers greater than or equal to -4.
Step-by-step explanation:
The domain of the function y = sqrt(x + 4) is all real numbers greater than or equal to -4.
To find the domain, we must determine the values of x that make the function defined.
- The square root function is defined only for non-negative values. Therefore, x + 4 must be greater than or equal to 0.
- Solving the inequality x + 4 ≥ 0, we get x ≥ -4.
Therefore, the domain of the function is x ≥ -4.
