Domain

The set of all possible values which qualify as inputs to a function is known as the domain of the function, or it can also be defined as the entire set of values possible for independent variables.
- The domain can be found in – the denominator of the fraction is not equal to zero and the digit under the square root bracket is positive. (In case of a function with fraction values).

For e.g. the domain of the function F is set A i.e. {India, Pakistan, Australia, Sri Lanka}.
