Domain and Range Calculator
Top
Domain and Range Calculator helps us to find the values of the domain and range for a given function. It will also give us the graph of the range and domain for the given function. You have to enter the function in the given space so that you will get the domain and range of the given function once you click on submit.
We have combined both Domain Calculator and Range Calculator, so that you can get both domain and range values together.

## Step by Step Calculation

Step 1 :

Observe the given function

Step 2 :

Find the domain and range of the given function based on the defined interval notation.

## Example Problems

1. ### Find the Domain and Range of of $\frac{1}{(x-1)}$

Step 1 :

Given function $\frac{1}{(x-1)}$.

Step 2 :

If we give the value of x as 1, it will the denominator as zero. So the value of the function will become infinity. so, the domain of the given function will be

Domain {x belongs to R : x$\neq$1}

Range {y belongs to R : y$\neq$0}

2. ### Find the Domain and Range of x2-2.

Step 1 :

Given function is x2-2.

Step 2 :

The set of entire real numbers will be the domain of the given function and the range will vary based of the function f(x). Since we assumed the value of x as rel number, x2 value will become zero or above. Hence x2 > = 0. subract 2 from both sides to get the desired expression. Hence the Range will exist above -2.
