1. The problem is to find how to stop or limit a graph on Desmos at the points where $x=0$ and $y=0$. 2. On Desmos, to restrict the domain or range of a function, you use curly braces with conditions. 3. For example, if you have a function $y=f(x)$ and want to stop it at $x=0$, you write: $$y=f(x)\{x \leq 0\}$$ This means the function is only graphed for $x$ values less than or equal to 0. 4. Similarly, to stop the graph at $y=0$, you can restrict the range by writing: $$y=f(x)\{y \geq 0\}$$ which means only plot points where $y$ is greater than or equal to 0. 5. If you want to restrict both $x$ and $y$ simultaneously, combine the conditions with commas: $$y=f(x)\{x \leq 0, y \geq 0\}$$ This restricts the graph to the region where $x \leq 0$ and $y \geq 0$. 6. This way, the graph will stop or be limited at the lines $x=0$ and $y=0$ as desired. 7. Remember, you can adjust the inequalities ($\leq$, $\geq$, $<$, $>$) depending on exactly where you want the graph to stop. This is how you control the domain and range on Desmos to stop the graph at specific $x$ and $y$ values.
