Hi every body i hope you're all going well
I have a great problem i don't know how to inverse a function in the graph with my casio fx-9860g sd
i know how to do it manually
and i also know how to make it using a ti-83+
but please i wanna really know how to do it using my beloved casio fx-9860G SD
for your information here is how to do it using the ti-83+ :
this is just an example
Y1=2X+4
2nd PRGM (DRAW)=>>8:DrawInv
vars>>Y vars>> Functions>> Y1
and here we can see the inverse on the graph
so please i wanna your help how can i do this with my casio calc???
thanks in advance

Shouldnt you just reverse the X's with the Y's?

so go to the graph function, prss f3, then f4, (Y1 changed to X1)
x1=2y+4.. might do the trick

edit:(no it doesnt, only works for vertical lines srry).

I tried that before posting that topic but it doesn't work as it doesn't recognise Y as a vriable if we reverse as you said in your edit
thanks anyway
but please i wanna the help of any body here please help me because i really need to be able to do that

I think you can do like this :


First, type your formula (Y1=2x+1), draw it and then press F4 (Draw) and F4 (Inv). It should draw the inverse.

Yep, that does work.

[polo961]

well thank you very much it worked but is there any way to make that work with the table??

[kucalc]

Now that I don't think you can do. I guess you would have to do it manually.
