Answer 2

The distance between the Earth and the Moon is increasing due to tidal forces. These tidal forces result in a transfer of angular momentum from the Earth's rotation to the Moon's orbit, causing the Moon to move farther away from the Earth at a rate of approximately 3.8 centimeters per year.

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.
