Question
**Problem Statement:**

Find a unit vector **u** that is normal to the level curve of \( f(x, y) = 5x^2y \) through \( P = (x, y) = (1, -4) \) at \( P \).

The figure shows the level curves of \( f(x, y) = ax^2y \).

**Graph Description:**

The graph depicts a series of hyperbolic level curves for the function \( f(x, y) = ax^2y \). The curves are centered around the origin, and they are symmetric with respect to both the x-axis and y-axis.

- The x-axis and y-axis are marked with points labeled \( a \) and \( -a \).
- The blue and purple curves increase in separation as they move away from the origin, illustrating the changing function values.
- A point labeled \( (x, y) \) is marked on one of the curves, indicating a specific location on the level curve of the function.
