Final answer:
The range of the function with a restricted domain of -4 ≤ x ≤ 4 is -4 ≤ y ≤ 4.
Step-by-step explanation:
The range of a function is the set of all possible output values, or y-values, that the function can produce for its corresponding input values, or x-values. In this case, the domain of the function is restricted to -4 ≤ x ≤ 4.
Since the function is a horizontal line, the range will be the same for all values of x within the domain. In other words, the range is the set of all possible y-values for which -4 ≤ y ≤ 4.
Therefore, the answer is option A: -4 ≤ y ≤ 4.
