I am not sure the precise meaning because of the ambiguity derived from \(\ldots\) and the difference of the numbers of "(" and ")", but the growth rate is roughly bounded by \(f_{\omega}^2(x)\) in FGH in any reasonable interpretation, I think. (Depending on the meaning, it could be smaller than \(f_4(x)\) in FGH.)
