rawExpression issue

I need to fix this old activity which used rawExpression. On screen 3 I need students to be able to choose to input the equation of either a quadratic, a cubic, or a circle. I’ve replaced rawExpression with simpleFunction, but I think that only accepts eg y=x^2 +3x-10 and not x^2 + y^2 = 25

Please send me your ideas!

You can use functions in terms of x and y using this format:

function(`f`): parseEquation(yourTableName.cellContent(1,2)).differenceFunction("x","y")

To display, in your graph (add restrictions if you need to):


Thanks so much for your response to both my questions Daniel. Apologies for the first post being a little unclear. I think I’ve got it working now.

Really appreciate your support!
