The following table lists the values of functions $f$ and $g$, and of their derivatives, $f'$ and $g'$, for the $x$-values $1$ and $2$.
$x$ | $f(x)$ | $g(x)$ | $f'(x)$ | $g'(x)$
:-: | :-: | :-: | :-: | :-:
$1$ | $4$ | $2$ | $3$ | $-2$
$2$ | $6$ | $1$ | $1$ | $0$
Let function $G$ be defined as $G(x)=f\Bigl(g(x)\Bigr)$.
$G'(2)=$ [[☃ numeric-input 1]]
