Hi, I need to use the anti-derivative for the function of f(x) = -4/3(x^3-1). I need to get to the first function equation. However, there is a slight, and by slight I mean major, issue. I do not know and was not taught how to use the anti-derivative law with fractions. I keep on getting closer to the answer but cannot get it. This is what I got for f(x') = 2/3(x^-3 - 1)^2.

What should I do next? f(x') is clearly incorrect.

Edit. I also got f(x') = 1/2(x^3 1)^-4. This is much closer, but still wrong.
