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

$x$	$1$	$-1$	$3$	$5$
$f(x)$	$1$	$3$	$-17$	$-99$
$g(x)$	$-1$	$5$	$-55$	$-253$
$f'(x)$	$-1$	$-5$	$-21$	$-65$
$g'(x)$	$-7$	$-7$	$-55$	$-151$

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