Answer:
(-∞, ∞)
Step-by-step explanation:
The domain of a function is the set of values of the independent variable for which the function is defined. On a graph, it is the horizontal extent of the graph.
The domain of any polynomial function is "all real numbers." There are no values of x for which f(x) is undefined.
In interval notation, the domain is ...
(-∞, ∞)
