Question

The domain of the function $$ f(x)=2 x^{3} $$ $$ \begin{array}{ll}	ext { A. } \quad[0, \infty) \ 	ext { B. } \quad R \backslash(0)\end{array} $$

The domain of $$ f(x) = 2x^3 $$ is all real numbers, $$ \mathbb{R} $$.

The domain of the function \( f(x)=2 x^{3} \) \( \begin{array}{ll}\text { A. } \quad[0, \infty) \\ \text { B. } \quad R \backslash(0)\end{array} \)
