anonymous · Answer

hey lugi can you see it now?

luigi0210 · Answer

Yes, and it's backwards.. but finding an inverse is easy. Just switch y and x and solve for y

anonymous · Answer

and how would i solve for Y

luigi0210 · Answer

Okay so you have 
y=x-1
Now switch them:
x=y-1
Now just solve for y

anonymous · Answer

$$f ^{-1}(y)=x+1$$

luigi0210 · Answer

Yup, easy right? :)

anonymous · Answer

ok but do i write it like this because i get the right answer but it tells me that itswrong im i suppose to write differently

luigi0210 · Answer

Hm, the way you write it is correct.. did they teach you differently?

anonymous · Answer

idk i got all of them wrongg man

luigi0210 · Answer

Oh, I think it might of been asking for just the inverse.. not the solved inverse..
So I think it just might of been x=y-1

luigi0210 · Answer

Which is $$f^{-1}(y)=y-1$$

anonymous · Answer

huh so its y-1?

anonymous · Answer

well its say complete the equation for the inverse

luigi0210 · Answer

Yea, the question isn't clear to me..

luigi0210 · Answer

Well hey, i have to go. Try opening a new question with the same problem and see if anyone else can answer it. Sorry i couldn't help.

anonymous · Answer

wait so ur best guesses are?

luigi0210 · Answer

And just an educated guess but #2 might be C

luigi0210 · Answer

See you now! @surjithayer might be able to help you from here :)

anonymous · Answer

Let f(x)=y
$$or x=f ^{-1}\left( y \right)$$

anonymous · Answer

y=x-1
interchange x and y
x=y+1
$$f ^{-1}\left( y \right)=x=y+1$$

anonymous · Answer

thanks
