Aghh… yes, I see what you mean! I changed the initialLatex to have it say f(x)= and that seemed to be the trick, it works. I didn’t think that starting text in the box was anything more than a “label” so I figured it could be whatever I wanted it to be. I wonder if there’s a way to make it work? I could do a workaround by making it a table instead (I think?) but I really like the way it looks as designed.
I was not sure about exactly what the line in the graph needed to be. In the sample I was using as a guide, there is a line for f(x) and another line that defines f(x) as a graph that is never visible - I’m not sure why? It looks like just having “f(x)” in the graph works fine, from my new testing.
OK, I’ve made some edits with a 2nd and 3rd screen. I believe that the link I used above now points to the updated version. 2nd screen works as I originally intended, but it says “f(x)=” in the math input instead of f^-1. I suppose I could change the prompt to something like “let f(x) be the inverse of g(x)…” but that it more convoluted.
On screen 3, I do it with a table instead. That works, but again, I prefer my original plan. Would still love to know if there is a way to make it work!
