Question

dada as funções f(x)=4x ‐ 1 e g(x)=3x +2, determine

f(g(2))=

g(f(-3))=

Answer 1

$f(x) = 4x \\ f(g(2)) = 4 \: . \: (3 \: . \: 2 + 2) \\ f(g(2)) = 4 \: . \: (6 + 2) \\ f(g(2)) = 4 \: . \: 8 \\ \boxed{\boxed{\boxed{f(g(2)) = 32}}} \\ g(x) = 3x + 2 \\ g(f( - 3)) = 3 \: . \: 4 \: . \: ( - 3) + 2 \\ g(f( - 3)) = - 9 \: . \: 4 + 2 \\ g(f( - 3)) = - 36 + 2 \\ \boxed{\boxed{\boxed{g(f( - 3)) = - 34}}}$
