Yes, the equation xy = 4 is a direct variation equation. The constant of variation, represented as k, is calculated by dividing one variable by the other: k = y/x. Therefore, in this equation, k = 4/x.

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.
