Continuity and Differentiability 31.12.08 - NCERT
ncert.nic.in › ncerts › lContinuity of f at a means lim ( ) x a f x → + = f(a) and continuity of f at b means – lim ( ) x b f x → = f(b) Observe that lim ( ) x a f x → − and lim ( ) x b f x → + do not make sense. As a consequence of this definition, if f is defined only at one point, it is continuous there, i.e., if the domain of f is a singleton, f is a ...
