Final answer:
The domain of the function with points (-2,1) and (4,1) is all real numbers.
Step-by-step explanation:
The domain of a function represents the set of all possible input values (x-values) for which the function is defined. In this case, the given points are (-2,1) and (4,1). Since both of these points have the same y-value of 1, the function is horizontal with a constant output value of 1. Therefore, the domain of the function is all real numbers.
