3rd derivative of y with respect to x, any other variables are considered constants (although it doesn't matter here since you only HAVE one variable).
answer is below... if you have white background, highlight to read...
Mathematica says:
-384*(3x-4)/(4x+2)^4+288/(4x+2)^3
for an input of "D[(3x - 4)/(4x + 2), {x, 3}]", if that helps any. ;)

I can't get the first half to save my life... is this the right second derivative?
(288x-32)/(4x+2)^3

First derivative: 11/(2[2x+1]^2)
Second derivative: -22/[2x+1]^3
Third derivative: 132/[2x+1]^4
