Question

Salut, vreau si eu rezolvarea acestui exercitiu + formulele folosite. Multumesc!

Answer 1

$f : \mathbb_{R} \rightarrow \mathbb_{R} , \quad f(x) = x+2016 \\g : \mathbb_{R} \rightarrow \mathbb_{R} , \quad g(x) = x-2016 \\ \\ \Big(g o f\Big) \Big(0\Big) = g\Big(f(0)\Big) = g(0+2016) = g(2016) = 2016-2016 = 0$
$\Rightarrow \boxed{\Big(g o f\Big) \Big(0\Big) = 0}$

$\ Formula folosita: \Big(u o v\Big)\Big(a\Big) = u\Big(v(a)\Big)$
