Question

F(x) = 12/(4x+2). Lets say we're finding the inverse

f(x) = 12/(4x + 2)
y = 12/(4x + 2)
4x + 2 = 12/y
4x + 2 * 12 = y
4x + 24 = y

Now, we could just replace x and y
4y + 24 = x

Answer 2

Are you asking a question? If you are finding the inverse; you should swap X and Y in the 2nd line...

Answer 3

Hmm? Why?

Answer 4

Maybe I should say it like this..
Swap F(x) with Y - as you did
now solve for X

then switch the variables

Answer 5

Yes you did all of that and yes, just swap the variables as you stated. Sorry for the confusion

Answer 6

F(x) = 12/(4x+2).

y = 12/(4x + 2)
4x + 2 = 12/y
4x + 24 = y
4y + 24 = x

Answer 8

Your line 3 is incorrect

Answer 9

4x +2 = 12/y
4x = 12/y -2
x = 3/y - 1/2

now swap
y = 3/x - 1/2

Answer 10

Oh, I see :)

Answer 11

You are welcome.
