Desmos is a free online graphing calculator that can be used to plot a variety of functions, including polynomials, trigonometric functions, and rational functions. The domain of a function is the set of all possible input values for which the function is defined. In other words, it is the set of all x-values for which the function will produce a y-value. To show the domain of a function on Desmos, you can use the “domain” command. For example, to show the domain of the function f(x) = x^2, you would type the following into the Desmos input bar:
domain(x^2)
