Question

se f(x)= 5x - 2 e h(x)= 2 - 3x. calcule f(f(x)) e h(h(x)).

Answer 1

$\boxed{f(x) = 5x-2} \\\\ f(f(x)) = 5f(x)-2 \\\\ f(f(x)) = 5(5x-2)-2 \\\\ f(f(x)) = 25x-10-2 \\\\ \boxed{\boxed{f(f(x)) = 25x-12}}$

E o segundo:

$\boxed{h(x) = -3x+2} \\\\ h(h(x)) = -3h(x)+2 \\\\ h(h(x)) = -3 \cdot (-3x+2)+2 \\\\ h(h(x)) = 9x-6+2 \\\\ \boxed{\boxed{h(h(x)) = 9x-4}}$
