##### Condition for Continuity of a Function

If the left hand limit (LHL), right hand limit (RHL) and the value of function at any point is same, the function is called a continuous function at that point. For the functions containing modulus function, it is better to redefine the function on the basis of the range of modulus and then check the continuity of the function. Polynomial function, sine, cosine functions are always continuous at all real values. If any function is already continuous, then we can find the unknown values (just like question number 26 to question 29), by using the relation LHL = RHL = f(x) at the point where the function is continuous.

### When a function is said to be continuous at a point?

A function is continuous at x = c if the function is defined at x = c and if the value of the function at x = c equals the limit of the function at x = c.

### Check the continuity of the function f given by f (x) = 2x + 3 at x = 1

The LHL and RHL for the function at x = 1 are equal, therefore the function is continuous at x = 1.

### When does a real function f is said to be continuous?

A real function f is said to be continuous if it is continuous at every point in the domain of f.

### If two functions are continuous at a particular point, then what can you say about the sum and difference of functions?

Suppose f and g be two real functions continuous at a real number c. Then f + g is continuous at x = c and f – g also is continuous at x = c.

### Which problems of exercise 5.1 of class 12th Maths are expected for the board exams?

Exercise 5.1 of class 12th Maths has 20 examples (examples 1 to 20) and 34 questions. All the problems of this exercise are important and can come in the board exam, but the most important problems of exercise 5.1 of class 12th Maths are examples 4, 5, 7, 9, 11, 14, 15, 16, 17, 18, 19, 20 and questions 3, 5, 7, 9, 15, 17, 18, 19, 22, 24, 26, 28, 30, 31, 32, 33, 34. 2 to 3 marks question can come from this exercise.

### Can students do exercise 5.1 of class 12th Maths in 5 days only?

Students can do exercise 5.1 of class 12th Maths in 5 days or not depends on student’s working speed, efficiency, capability, and many other factors. But if they try to do exercise 5.1 of class 12th Maths in 5 days, they can easily do that.

### Which is the core topic to study in exercise 5.1 of CBSE 12th Maths?

In exercise 5.1 of grade 12th Maths, students will study:
1. Continuity
a. Suppose f is a real function on a subset of the real numbers and let c be a point in the domain of f. Then f is continuous at c if

b. If f is not continuous at c, we say f is discontinuous at c and c is called a point of discontinuity of f.
c. A real function f is said to be continuous if it is continuous at every point in the domain of f.

2. Algebra of continuous functions
Theorem 1: Suppose f and g be two real functions continuous at a real number c. Then:
(1) f + g is continuous at x = c.
(2) f – g is continuous at x = c.
(3) fg is continuous at x = c.
(4) (f/g) is continuous at x = c, (provided g (c) ≠ 0).

Theorem 2: Suppose f and g are real valued functions such that
(f o g) is defined at c. If g is continuous at c and if f is continuous at g (c), then (f o g) is continuous at c.

### Is exercise 5.1 of class 12th Maths easy to solve?
