Consider the relation defined by the equation $2x^2 + y = 12$.
(a) Does this equation represent $y$ as a function of $x$? If so, express $y$ as a function of $x$.
Yes, $y = f(x) =
$
No, $y$ cannot be represented as a function of $x$.
(b) Does this equation represent $x$ as a function of $y$? If so, express $x$ as a function of $y$.
Yes, $x = g(y) =
$
No, $x$ cannot be represented as a function of $y$.
