Every function will have two important aspects called the domain and the range. It is not that difficult to understand the basics of these aspects, but the involvement of numerous other elements will often leave you confused. You may even end up finding incorrect or incomplete domain or range, but fortunately, you can avoid running into trouble by using our domain and range calculator online.

The first thing you will learn about this concept is that the 'X' variable used to definite the domain of a function, whereas the range of a function is defined by the 'Y' variable. The domain is the set of input values of X, whereas the range is the set of output values of Y. Sometimes, it is easy to enter any value of X and still get a valid answer - the domain in this case will be over all of the real numbers. The same is the case with range, as you can find any output Y value and the range in this case is over all of the real numbers. You find yourself in trouble when it doesn't work like this, and that's when you can overcome the challenge by using domain and range of a function calculator.

The topic becomes even difficult when you have to identify which numbers of the domain or range are not allowed - you will also have to ensure you've presented the solution in the correct notation. You can stay out of trouble by using this online domain calculator that not only helps you find the correct answer, but also hones your skills to definite ranges and domains with more authority. The use of this domain and range calculator will also ensure that you've found the correct answer. Above all, the calculator is designed to identify forbidden numbers as well. So, just enter the function and click the 'Find the Equation Domain and Range' in the calculator to find the solution. Try it today to improve your knowledge and understanding of domains and ranges.

Calculate domain and range step by step

The calculator will find the domain and range of the single-variable function.

Enter a function of one variable:

Enter an interval:

Required only for trigonometric functions. For example, `[0, oo)` or `(-2, 5pi]`. If you need `oo`, type inf.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your input: find the domain and range of $$$f=\frac{1}{x - 1}$$$

Domain

$$$\left(-\infty, 1\right) \cup \left(1, \infty\right)$$$

Range

$$$\left(-\infty, 0\right) \cup \left(0, \infty\right)$$$

Graph

How do I find the domain and range of a function?

How to Find The Domain and Range of an Equation? To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

How do you find the range of a function on a calculator?

The procedure to use the domain and range calculator is as follows:.
Step 1: Enter the function in the input field..
Step 2: Now click the button “Calculate Domain and Range” to get the output..
Step 3: Finally, the domain and range will be displayed in the new window..

How do you find the domain and range on Desmos?

To find the domain and range in Desmos, start by graphing the function. Then, use the trace tool to identify the x- and y-values of the points on the graph. The domain is the set of all x-values, and the range is the set of all y-values.

What is the domain and range of a graph calculator?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
