Mathematics is one of the vital subjects that need to be studied by students. Many people don’t even notice but there are many different places where we use the concepts of maths. Math is a tool that has been used for a long time to shape our world. There are many things that we are using today and a lot of applications of mathematics have been used in them to make it possible for the real world.

Many students dislike this subject and the reason behind it is that the concepts of maths are hard to understand and master. Math consists of a vast number of concepts and all of them are equally important. In this article, we will be discussing the __domain and range__ of a function. Which is considered one of the most important topics in mathematics.

It is crucial to understand function before we move to domain and range. One can define a function as a special type of relation. We can define a function as a relation between a particular set of inputs and outputs. In a function, each value of the input is related to exactly one output. Let us take an example to understand the concept of functions.

Let the set of input values be 1, 2 and 3 and there be few values in the output set. If a set has to be referred to as a function. Then for all the values that are 1,2 and 3, there should be a value present in the set of output and each input is related to exactly one value in the output. Now let us discuss in detail the domain and range of a function.

- Domain: The domain of a function is the collection of inputs to the function. There are two approaches for determining a function’s domain. Algebra is one of the approaches for determining the domain. The alternative method is to use graphs to find it. Aside from using a correct procedure, there are a few more methods for locating the domain. Consider the case when we need to determine the domain of a fractional function. When the function is in fraction form, the denominator must be set to zero in order to obtain the variable’s value. The values we’ve obtained are no longer part of the domain of a fractional component. Similarly, there are numerous methods for determining a function’s domain.
- Range: The set of all the outputs of a function is called the range of a function. One can also say that the collection of all the output that we get on entering a specific set of input is called the range of a function. There are many ways of finding the range of a function. An exponential number always gives us the range of positive real numbers and the range of a function that has a square root is always a value that is not negative because the square can’t be negative. Similarly, we can find a range of many other kinds of functions

Domain and range are crucial topics of mathematics. Students need to understand these topics in detail and clear all the basics related to the topic, as domain and range have a lot of applications in our real life. These concepts are not only useful in mathematics but in other subjects also it has a huge impact. Every student needs to do a lot of practice to master these topics.

In the above article, we have tried to discuss all the important concepts related to domain and range. Learning of these topics should be done properly. To give the right direction to students there are a lot of platforms available online. These platforms are best for students to learn and master such topics. One such platform that is doing exceptionally well in educating children is __Cuemath__. It is a very good option for children, as it becomes very easy to learn math-related topics from Cuemath. Not only children but anyone who wants to learn and clear the concepts of mathematics should consider Cuemath.
