Then f is continuous at c if lim ( ) ( ) x c f x f c → = More elaborately, if the left hand limit, right hand limit and the value of the function at x = c exist and are equal to each other, i.e., lim ...

In other words polynomial, rational, algebraic, trigonometric, exponential, logarithmic, hyperbolic trigonometric, etc… discussed in 2.4 are continuous where their formulas make sense. If we are not at a vertical asymptote or
CONTINUITY - Pennsylvania State University
www.personal.psu.edu › class › Math140ACONTINUITY Definition: A function f is continuous at a point x = a if lim f ( x) = f ( a) x → a In other words, the function f is continuous at a if ALL three of the conditions below are true: 1. f ( a) is defined. (i.e., a is in the domain of f .) 2. lim f ( x) exists. (i.e., both one-sided limits exist and are equal at a.) x → a 3.
Continuity and Differentiability 31.12.08
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 ...
Continuity and Uniform Continuity

Therefore jf(x) f(x 0)j<". so the expression for can only involve "and must not involve either xor x 0. It is obvious that a uniformly continuous function is continuous: if we can nd a which works for all x 0, we can nd one (the same one ...
