Answer
$y$ is a function of $x$
Work Step by Step
Solve for $y$.
Factor out $y$ on the left side of the equation to obtain:
$y(x+2)=1$
Divide $x+2$ on both sides to obtain:
$\dfrac{y(x+2)}{x+2} = \dfrac{1}{x+2}
\\y = \dfrac{1}{x+2}$
Note that when you assign any real number value (except -2) to $x$, the equation will give only one value of $y$.
Thus, the given equation represents $y$ as a function of $x$.
