Question 22532
That's fine so far.
Now interchange x and y to form the inverse.
y^2=yx-x
It's not very pretty but that is the inverse.
You would like to write that as y= something
but you can't.  So leave it as it is.

You could have done that interchance on the original
form of the equation and just left it that way.
