$y$ is a function of $x$
Work Step by Step
Solve for $y$. Add $y$ on both sides of the equation to obtain: $|x|=2+y$ Subtract $2$ on both sides to obtain: $|x|-2=y$ 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 $x$.
