1.8.11 Differential equations with separable variables (A-level only)

A curve, $C$ , passes through the point with coordinates $(2, 4)$ . The gradient of $C$ at any point $(x, y)$ is given by

\frac{dy}{dx} = \frac{x^2 y^2}{4}

Show that $C$ intersects the coordinate axes at exactly one point and state the coordinates of this point. Fully justify your answer.
