If you intend to havethevalues under the first column to be equally spaced, but are too lazy to enter the values yourself manually, then you can auto-fill the first column by pressingEnterrepeatedly after entering the first two values into thecolumn. In fact, the restriction(s) could have been any number of equations/inequalities, involving anycombination of thedesignated variables(e.g., $x$, $y$, $r$, $\theta$), with thecaveatbeing that the variables in the restrictions need to becompatible with the equation/inequality they are restricting in the first place (e.g., a polar equationcan only be restricted usingthepolar variables $r$ and $\theta$). To see that, just click on the "Edit Graph" section that is shown on the picture you attached earlier. Being primarily a graphing calculator in nature, Desmos seems to prefer presentinga new table withtwo humble columns by default: the first column $x_1$ presumably for the $x$-values, and the second column $x_2$ for the $y$-values. Students can do this by hand or use a calculator. How can I graph a piecewise function in Desmos. In fact, working on a graph while logged in allows you to give a title to the graph, so that if you decide to save it for later, a simple Ctrl + S will do. Feel free to post demonstrations of interesting mathematical phenomena, questions about what is happening in a graph, or just cool things you've found while playing with the graphing program. In which case, one can always choose tosegment the graphby imposing restrictions on theequation/inequality in question as long as the following syntax rule is being adhered to: \begin{align*} \text{equation/inequality} \, \{ \text{condition 1}\}\{ \text{condition 2} \} \ldots \end{align*}.
