The Intermediate Value Theorem
Continuity a function is considered continuous at x = c if the following three conditions are met:
• f(c) is defined (i.e. a real number)
• the limit of f at c exists • the limit of f at c is the value of f(c)

Discontinuity exists in two forms:
Removable if f(n) can be defined and restore EC nature
Nonremovable if f(n) can not be defined and restore EC nature
