One-Sided Limits: One-sided limits are limits that approach a specific value from either the left side or the right side of a function. They determine what value a function approaches as x gets closer to a certain point from one direction only.
Continuity: Continuity refers to functions that have no breaks, holes, or jumps in their graphs; they can be drawn without lifting your pencil.
Asymptote: An asymptote is an imaginary line that defines where the graph gets infinitely close to but never reaches.
