Ok, there are two main ways, using CL or calculating in the graph. Here are examples of each. Let me know if anything is unclear.
Also, in case you don’t know, the easiest way to create the LaTex for an expression (in my opinion) is to type up the expression in desmos, either the graph or in a math response box, and then copy it. When you paste it into CL, it will paste in correctly formatted LaTex.
