For a function to be continuous at a point, it must be defined at that point, its limit must exist at the point, and the value of the function at that point must equal the value of the limit at that point. Discontinuities may be classified as removable, jump, or infinite.
Do limits always exist in continuous functions?
No, a function can be discontinuous and have a limit. The limit is precisely the continuation that can make it continuous. Let f(x)=1 for x=0,f(x)=0 for x≠0.
How do you find the limit of a continuous function?
- f(c) must be defined. ...
- The limit of the function as x approaches the value c must exist. ...
- The function's value at c and the limit as x approaches c must be the same.
