for ex. i put the function X^2+2 on y. y:=x->x^2+2
how can i display what function is behind y later? of course i always could scroll up to the point where i defined it, but is there a shorter way? with variables, you enter them and see their value. it something similar possible with functions?
i now that i can see the function inmy example with y(x), but what if you have a function with 5 more?
thanks for help
