Question 172199
The domain and range of ANY cubic is all real numbers since any "x" value can be plugged into the cubic (there is no division by zero or square roots to worry about).



Also, it turns out that cubic functions are <a href="http://en.wikipedia.org/wiki/Surjective_function"><i>onto</i></a> functions. In other words, the range of cubic functions is all real numbers.



So we have:



Domain: all real numbers which in interval notation is *[Tex \LARGE \left(-\infty,\infty\right)]



Range: all real numbers which in interval notation is *[Tex \LARGE \left(-\infty,\infty\right)]
