Question

Find the inverse of f(x) = 3x / (2x + 1)

So I know the process of doing this: replace f(x) with y, switch y and x, solve for y. But I can't seem to do it for this one.

Answer 1

x = 3y/(2y+1)

so we need to isolate 'y',
which step are you stuck?

next step : x (2y+1) = 3y

distribute x

Answer 2

@hartnn Yes I did this and then I got confused.
