Infinity, denoted as ∞, represents a value that is unbounded or limitless in magnitude. Plus infinity (+∞) signifies values that are larger than any finite number, while minus infinity (-∞) represents values that are smaller than any finite number.

L is the limit of the function f at the point a if: the output goes towards L as the input gets closer to a.
