Domain and Range Calculator

The Domain and Range Calculator is a tool designed to help you determine the domain and range of a function. Whether you're studying calculus, algebra, or another discipline, our calculator gives you an accurate understanding of the fundamental concepts of domain and range.

How to Use the Domain and Range Calculator?

• Input

  Enter the function you want to analyze into the provided input field. Make sure to use proper mathematical notation and symbols.

• Calculation

  Click the "Calculate" button to process the function. Our calculator will analyze the function and determine its domain and range.

• Result

  The calculator will display both the domain and the range of the function. The domain consists of all possible x-values for which the function is defined, while the range consists of all possible y-values that the function can produce.

What Is Meant by Domain and Range?

Domain and range are fundamental concepts that give insight into the behavior of functions. They help determine the values for which the function is valid and the values it can produce as output. Understanding domain and range is essential for interpreting functions and their properties.

Domain

The domain of a function is the set of all possible input values (x-values) for which the function is defined and produces meaningful results. In other words, it represents the range of values that the function can take and produce a valid result out of. A function may have restrictions on its domain due to mathematical limitations or practical considerations.

The domain of a function $$$f$$$ is often denoted as $$$D(f)$$$ and can be expressed using interval notation, inequalities, or other relevant mathematical representations.

Range

The range of a function is the set of all possible output values (y-values) that the function can give within its domain. It represents the set of values that the function can produce as its output. The range gives an idea of the vertical extent of the graph of the function and the variety of its output values.

The range of a function $$$f$$$ is denoted as $$$R(f)$$$ and can be described using interval notation, inequalities, or other appropriate mathematical forms.

Example

Consider the function $$$f(x)=\sqrt{x}$$$, which represents the square root of $$$x$$$. The domain of this function would be all non-negative real numbers, i.e. $$$x\ge0$$$, as the square root is undefined for negative values. The range also consists of all non-negative real numbers, i.e. $$$f(x)\ge0$$$, since the square root of any non-negative number produces a non-negative result.
