$y$ is a function of $x$

Work Step by Step

Solve for $y$. Add $-x$ on both sides of the equation to obtain: $y^3=-x+8$ Take the cube root of both sides to obtain: $y=\sqrt[3]{-x+8}$ Note that when you assign any real number value to $x$, the equation will give only one value of $y$. Thus, the given equation represents $y$ as a function of $x$.
