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

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

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