Continuity & Differentiability

This calculus video tutorial provides a basic introduction into continuity and differentiability.  Continuity tells you if the function f(x) is continuous or discontinuous at some point in the interval (a,b).  Points of discontinuity include holes, jump discontinuities, and infinite discontinuities.  A hole is considered a removable discontinuity.  Jump and infinite discontinuities are considered nonremovable discontinuities.
