CBSE Class 12 Maths Notes Chapter 5 Continuity and Differentiability Continuity at a Point: A function f(x) is said to be continuous at a point x = a, if Left hand limit of f(x) at(x = a) = Right hand limit of f(x) at (x = a) = Value of f(x) at (x = a) i.e. if at x = a, LHL = RHL = f(a) where, LHL = and RHL = Note: To evaluate LHL of a function f(x) at (x = o), put x = a … [Read more...]
