Continuity
Function has different functional and limiting
values at x =c
Discontinuous: as f(x) is not
defined at x = c
Discontinuous: as f(x) has a gap
at x = c.
Discontinuous: not defined at x = c.

Continuity
Proof
(c) F is continuous at x = a,b
Example
(a) F is discontinuous at x = a
(b) F is discontinuous at x = b

This equation cannot be solved readily
by factoring because the left side has
no simple factors.
