#### 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.
