This problem tests calculating new functions from old ones:
From the table below calculate the quantities asked for:

$x$	$-2$	$4$	$2$	$1$	$-1$
$f(x)$	$19$	$-41$	$-5$	$-2$	$4$
$g(x)$	$-10$	$68$	$10$	$2$	$-2$
$f'(x)$	$-22$	$-34$	$-6$	$-1$	$-9$
$g'(x)$	$13$	$49$	$13$	$4$	$4$

$(f/g)'(-1)$
$f(-1) /( g(-1) +5)$
If $h(x)=f(f(x))$, calculate $h'(-1)$
$(f g)(1)$
$(f+g)'(-1)$
