Hello,
I am trying to solve the problem below where I am attempting to find the derivative of an intergral. I tried the answer that is typed in but that is incorrect.
Any ideas? Thanks!

No need for this hint, Just apply the following formula:
If $\displaystyle g(x)=\int_{m(x)}^{h(x)} f(u) du$ where m and h are differentiable functions.
then: $\displaystyle g'(x) = f(h(x)) h'(x) - f(m(x))m'(x)$.
In your question:
$\displaystyle f(u)=\frac{u+2}{u-4}$.
$\displaystyle h(x)=3x$.
$\displaystyle m(x)=9x$.
