Thank you for the opportunity to help you with your question!

f(x) =x^3-4x + 8   (i hope this is the question)

domain is the set of all input values(x) for which there is a defined output

here every real value of x has a defined output

so domain = all real values of x ranging from negative infinity to positive infinity


domain = ( - ∞ , +  ∞) 



Please let me know if you need any clarification. I'm always happy to answer your questions.....thank you
