Given function to us is ,

$\implies f(x) = 3x^3 - 5x + 1$

The domain of the expression will be all real numbers except where the given expression is not defined . Therefore , the domain is ,

$\underline\text{ In Interval Notation :- }$

$\implies \boxed{ Domain : ( -\infty , +\infty ) }$

$\underline\text{ In Set Builder Notation :- }$

$\implies \boxed{ Domain : \{ x | x \in \mathbb{R} \}}$
