Question
Check if the relation given by the equation represents $y$ as function of $x$.

$x^2-y=25$

✓

Answer

$x^2-y=25$
$\therefore \mathrm{y}=\mathrm{x}^2-25$
$\therefore$ For every value of $\mathrm{x}$, there is a unique value of $\mathrm{y}$.
$\therefore \mathrm{y}$ is a function of $\mathrm{x}$.
