Suppose g(x) = (x-4/x-6)

Evaluate g-1(2)

I started by replacing X with Y and vice-versa...

I got

x = (y-4/y-6)

I cross multiplied... ented up with

y-4 = xy - 6x

I couldn't figure out where to move from there because of the xy and having a y on the other side...

...I'm supposed to replace the x's with 2, aren't I? -_-

When you replace 'x' with -2 and solve, what do you get?

Yeah, I think you've got it now. :)
