1. The user asks what to put into Desmos. 2. Desmos is a graphing calculator where you input functions to visualize them. 3. To use Desmos, you enter a function like $y=x^2$ or $y=\sin(x)$ in the input box. 4. For example, to graph a quadratic function, type $y=x^2$. 5. To graph a linear function, type $y=2x+3$. 6. You can also graph more complex functions like $y=\frac{1}{x}$ or $y=\sqrt{x}$. 7. Desmos will automatically plot the graph and show intercepts and extrema if enabled. 8. So, what you put into Desmos is simply the function you want to graph, written in standard mathematical notation using $x$ as the variable.
