#### Answer:

Domain: All real numbers

Range: All real numbers

#### Explanation:

Every cubic function like this has a domain and range of all real numbers, meaning that there are no hole, vertical asymptotes, or any type of discontinuities.

So if you see a polynomial that doesn't have an x in the denominator and no restrictions already put on it, then it will always have a domain and range of all real numbers. Let me know if you need clarification on anything
