Mathematical treatment of continuity starts with the definition of a function continuous at a point; this definition is given here in terms of a limit of a function at a point. In this chapter we shall develop the theory of limits of functions, study continuous functions, and particularly ...
If f is a polynomial or a rational function and a is the domain of f, then Example: Evaluate the following limits Solution: How to calculate the limit of a function using substitution? Show Video Lesson Functions with Direct Substitution Property are calledcontinuous at a. However, not all ...
was the case in functions of one variable, continuity is “user friendly”. In other words, if k is a real number and f and g are continuous functions at (a,b) then the functions below are also continuous at (a,b): 0 b) g(a, if ) , ( ) , ( ) , ( / )] , (...
limits are used to make all the basic definitions of calculus. for example, limits are used to define continuous functions. the conventional definition of a limit implies that every function is continuous at every solitary point of its domain. q5 what is the concept of continuity? in general,...

Limits of Functions:The limit of the continuous function that has the limit at some point, will be the value after substituting the point with the variable. The limit is not determinable in case of the jump discontinuity.Answer and Explanation: ...
