Question 908886
This is a polynomial function. The domain of any/every polynomial function is the set of all real numbers since you can plug in any real number for x without any restriction. You don't have to worry about dividing by zero, taking the square root of a negative number, etc etc.



So the domain of f(x) is the set of all real numbers.



The domain in interval notation is *[Tex \Large \left(-\infty,\infty\right)]
