How does knowing the period of variability of a Cepheid Variable star allow us to determine its absolute magnitude?
There is a relation between pulsation period and luminosity.

We can determine the absolute magnitude of Cepheid Variable stars by establishing a correlation between their intrinsic brightness and pulsation period through the period-luminosity relationship.

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.
