Using the inverse proportionality relationship (y \propto \frac{1}{x}), we can set up the equation (y_1 \cdot x_1 = y_2 \cdot x_2). Substituting the given values, we get (4 \cdot 3 = 12 \cdot x_2). Solving for (x_2), we find (x_2 = \frac{4 \cdot 3}{12} = 1). Therefore, when (y = 12), (x = 1).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
