Domain is "All Real Numbers" unless there is some reason for
it to be restricted. Since the given function `f(x)= 2x^3 -5x^2 +3x` is a polynomial function, then there is no restriction in the values of x.

Therefore, the domain is all real numbers. In interval notation, it is expressed as `(-oo,oo)` . And in set builder notation, the domain is `{x|x in RR} ` .
