Weblim x → a f ( x) = lim g ( t) → a f ( g ( t)). which is a generalized version of ( 2). If a limit of a function exists, then you can define your function to be continuous there. And then if you make a continuous change of variable, you get that continuity preserves the limit, e.g. lim x → 1 is the same as lim t → 0.
