how to calculate the domain of a function

-->

Function is a tool that is used to verify the relationship among given values. Now we will understand the concept how to find the domain of a function. Before finding the domain of any function and relation first of all we will learn about the domain of a function.

Set of inputs for a function is called as domain of function. Similarly we can say that set of all possible outputs corresponding to inputs is as known range of function. This concept can be understood with help of an example:

For example: Suppose we have some values (16, -51), (-19, 41), (110, -91), (-105, 198), find the domain of the given elements?

Solution: According to the definition of domain of function we can choose the domain values of above function.

Domain of a given function = 16, -91, 110, -105. Range of a function is given as:

Range is all ‘y’ coordinate values,

Range = - 51, 41, -91, 198.

Domain can be found using steps shown below:

Step 1: To calculate value first take a function or a relation which has ‘x’ and ‘y’ values.

Step 2: As we see above domain of function or relation is all input values.

This is how we can find the domain and range value of a given function and relation.

Multiplying Rational Expressions gives us a simplest form of any rational expression.
