How do gaseous planets form?
Identically to the way the rocky planets formed, gravity.
Gravity's effect upon the particles that went into forming the first four planets was greater in two ways: first, the mass of the particles that went into forming the rocky planets was greater than that of gas; second, as the hot particles pooled, they formed the first four planets; and third, as their individual gravity grew, they in turn drew in more particles making them larger and larger. This is why you have four rocky planets near the sun, followed by the gas giants.
While Jupiter is 318 times larger than Earth, its total mass is only 2.5 times larger. The gases that make up the gas giants were drawn into rapidly cooling solid gas balls. Jupiter, for example, is 90% hydrogen and the rest helium, much like a star.
Furthermore, Jupiter's gravity is only 2.4 times that of Earth, despite its 318-fold larger size.

Gas and dust particles in a protoplanetary disk gradually come together due to gravity; once a core of sufficient mass forms, it attracts more gas and eventually forms into a gaseous planet. This process is known as accretion.

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.
