How is the intensity of an earthquake with magnitude 8 not twice the intensity of an earthquake with magnitude 4?
1 higher magnitude is a 10 times stronger earthquake so a magnitude 8 is 10,000 times stronger than a magnitude 4.

The intensity of an earthquake is measured on a logarithmic scale, specifically the Richter scale. This means that each whole number increase in magnitude represents a tenfold increase in measured amplitude (which correlates with energy release). So, an earthquake with a magnitude of 8 releases 1,000 times more energy than one with a magnitude of 5, not twice as much.

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.
