    $\begingroup$ You can use the chain rule to better define $f'(x)$ and $w'(x)$ $\endgroup$ – WaveX Dec 8 '16 at 16:46

There is something called chain rule. In your case $f(x)=g(h(x))$. So $f'(x)=g'(h(x))\cdot h'(x)$.

Therefore $f'(3)=g'(h(1))h'(1)=g(3)\times (-0.5)=2\times(-0.5)=-1$. Do the other one yourself.
