Answer

The equation defines $y$ as a function of $x$.

Work Step by Step

An equation defines $y$ as a function of $x$ if for every value of $x$, the equation gives only one corresponding value of $y$. Note that for all values of $x$, the equation will give only one value of $y$. This is because a number has unique cube root. Thus, the equation defines $y$ as a function of $x$.
