Functions

ContinuityA continuous function is a function for which, intuitively, small changes in the input result in small changes in the output. Otherwise, a function is said to be discontinuous. Mathematically, function f is said to be continuous at point x = a if: 1. f(a) is defined, so that f(a) is in the domain of f. 2. exists for x in the domain of f. 3. Discontinuities:
