Answer 2

To find the constant of variation for a direct variation including the given values (2, 4), divide the second value by the first value. In this case, 4 divided by 2 equals 2. So, the constant of variation is 2.

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.
