Both the domain and range would be (negative infinity, positive infinity).
Step-by-step explanation:
The function in this case is a line. The domain is all the x values. As the line goes on forever, it stretches from say past -1,000,000 to past 1,000,000. (That is just an example of large numbers that prove the domain involves both negative and positive infinity). The range is all the y values. As the line goes on forever, it keeps going both up and down all the way to infinity. Both would be in parentheses, because both positive and negative infinity are always in parentheses).
