Answer
$y$ is a function of $x$
Work Step by Step
Solve for $y$.
Add $-x$ on both sides of the equation to obtain:
$y^3=-x+27$
Take the cube root of both sides to obtain:
$y=\sqrt[3]{-x+27}$
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 $x$.
