find a formula for the inverse of the function:
f(x) = (4x-1)/(2x+3)
i substituted f(x) for x and tried solving, and i ended up with (3x+1)/2, but that doesnt check
any help would be appreciated..
so you want to solve for
.........multiplied both sides by
..........expanded the brackets on the left
..........added on both sides
.........factored out from the left hand side
and that's your inverse function
EDIT: Ah, I didn't see that you responded, galactus. But i'll leave what i did up since i used a different method
