No, ( y = x + 2 ) is not a direct variation equation. In a direct variation equation, the variables are directly proportional to each other and can be represented in the form ( y = kx ), where ( k ) is the constant of variation.

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.
