1. The problem asks for the domain and range of a function, but the function itself is not specified. 2. The domain of a function is the set of all possible input values (x-values) for which the function is defined. 3. The range of a function is the set of all possible output values (y-values) the function can produce. 4. Without the explicit function, we cannot determine the exact domain or range. 5. The options given for domain are: a. $(-\infty, 5]$ b. $(-\infty, 0]$ c. all real numbers 6. The options given for range are: a. $(-\infty, -5]$ b. $(-\infty, 0]$ c. all real numbers 7. To answer correctly, please provide the function or more information about it.
