Can someone help with this? Like always, I get stuck with something that doesn't match the choices like $\displaystyle \frac{\frac{2}{3+h}-\frac{2}{3}}{h}$
$\displaystyle \frac{\frac{2}{3+h}-\frac{2}{3}}{h}$
$\displaystyle \frac{1}{h}\left(\frac{2}{3+h} - \frac{2}{3}\right)$
common denominator ...
$\displaystyle \frac{1}{h}\left(\frac{6}{3(3+h)} - \frac{2(3+h)}{3(3+h)}\right)$
$\displaystyle \frac{1}{h}\left(\frac{6 - 2(3+h)}{3(3+h)}\right)$
finish it ...
