The range is more challenging to find because the nature of the function may pose limitations. Step 3: Finally, the domain and range will be displayed in the new window, In Mathematics, a domain is defined as the set of possible values “x” of a function which will give the output value “y”. In this online domain and range calculator, enter an expression with a variable 'x' and submit to know the domain value. In short, a domain is defined as the set of values for which the function f(x) is defined, whereas the range is defined as the set of values that the function takes. 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 x -axis. And, I can take any real number, square it, multiply it by 3, then add 6 times that real number and then subtract 2 from it. Another way to identify the domain and range of functions is by using graphs. Summary: The domain of a function is all the possible input values for which the function is defined, and the range is all possible output values. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. In this case, there is no real number that makes the expression undefined.
