Question

Questão 3-Dadas as funções exponenciais f(x) = 3x-2 + 5 e g(x) = 5x+2 - 12 determine 3. f(5) + g(2)​

Answer 1

$\large\sf{}f(x) = 3x - 2 + 5 \\ \large\sf{}f(5) = 3 \times 5 - 2 + 5 = 15 - 3 = {\large\boxed{\boxed{  { \large \sf 12}}}}$

$\large\sf{}g(x) = 5x + 2 - 12 \\ \large\sf{}g(x) = 5 \times 2 \times 2 - 12 = 20 - 12 = {\large\boxed{\boxed{  { \large \sf 8}}}}$
