1. The problem asks to find the domain and range of the numbers. 2. The domain of a function or set of numbers is the set of all possible input values (x-values) for which the function is defined. 3. The range is the set of all possible output values (y-values) that the function can take. 4. Since the problem does not specify a particular function or expression, we assume it refers to the set of all real numbers. 5. The domain of all real numbers is $$(-\infty, \infty)$$. 6. The range of all real numbers is also $$(-\infty, \infty)$$. 7. Therefore, the domain and range of the numbers are both all real numbers.
