Why does the Milky Way Galaxy's nuclear bulge contain many red giants and supergiants as opposed to dwarfs and other stars?
We do not know that to be true.
The truth is that most red giants are located in the center of our galaxy, a fact that has only recently been mapped by astronomers. However, astronomers at the Keck Observatory find that it is very difficult to observe the center of our galaxy because 1) it is extremely bright and individual objects (stars) are difficult to pin down because they are moving at great speeds, and 2) a great deal of cosmic dirt exists between us and the galaxy's center, further clouding our observations.
Due to their small size and relatively low luminosity, dwarf stars are difficult to detect away from the brightness of the center; therefore, it is possible that there are millions of dwarfs at the center, but we would not be able to detect them with current technology.

Because the nuclear bulge of the Milky Way Galaxy is made up of older stars that have run out of hydrogen fuel and evolved off the main sequence, it is home to a large number of red giants and supergiants.

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.
