#### Answer

We get the equation ${{x}^{2}}+y=10$ that defines $y$ as a function of $x$.

#### Work Step by Step

The equation is given below:
${{x}^{2}}+y=10$ …… (I)
So, from equation (I),
$y=10-{{x}^{2}}$.
Thus, for every value of $x$, there is exactly one value of $y$. Thus, the equation defines $y$ as a function of $x$.
Hence, we get the equation ${{x}^{2}}+y=10$ that defines $y$ as a function of $x$.
