Domain: $(-\infty,\infty)$ Range: $(-\infty,\infty)$

Since the function is a cubic function the domain is $(-\infty,\infty)$ The function range is also $(-\infty,\infty)$ because all negative x values stay negative extending the range to negative infinity and because all positive x values stay positive extend the range to infinity.
