So I am asked to find the inverse of the functon: f(x) = (4x-1)/(2x+3)
so y=f(x) and interchange x with y...
So I start by multiplying both sides by 2y+3 to get x(2y+3) = 4y-1
Now I am not really sure what to do. I tried making it 2y+3-4y = -1/x
then -2y = -1/x -3
and -y = (-1/x -3)/2
But I think this is still the wrong answer. Can anyone lead me onto the right track? Thanks!
