[(4x+6 / 3x-1) + 6 ] / [(12x+18 / 9x-3) -4]
I tried to format it the best way I could... on my paper, it looks more like:
I can't figure this out for the life of me..
I am trying to prove that these are inverse. So I want the whole thing to equal x.
I don't know what this process is called.. but I just know I have to do the
f(x) of f^-1(x)
f^-1(x) of f(x)
Well I took a test on this section today... I believe I made a 100.. there was one problem where I wasn't sure though, so I just hope I got it right.
The problem that I listed wasn't on the test.. the kind of problem was, but it was a much shorter version.
It was basically doing the f of f-1 and f-1 of f stuff.. Don't know the proper name though.
