For a polynomial function, specifically a cubic function, the domain is always all real numbers, which can be represented as \( (-\infty, \infty) \).
The range of a cubic function can be all real numbers (i.e., \( (-\infty, \infty) \)) or may have a minimum or maximum depending on the specific graph of the function. Given that you describe the graph as a cubic function, if it extends infinitely in both y-directions, the range would also be all real numbers.
Based on the options provided, the correct choice would be:
**Domain: \( (-\infty, \infty) \); Range: \( (-\infty, \infty) \)**
So the response is:
**Domain: (−∞, ∞); Range: (−∞, ∞)**
