Question

Dadas as funções f(x) = 2x + 2 e g(x) = 5x, calcule f(g(8))

Answer 1

Resposta:

f(x) = 2x + 2

f(g(x)) = 2.5x + 2

f(g(x)) = 10x + 2

f(g(8)) = 10.8 + 2

f(g(8)) = 80 + 2

f(g(8)) = 82

Explicação passo-a-passo:

Answer 2

g(x) = 5x

g(8) = 5.8 = 40

f(x) = 2x +2

f(g(8))= 2.g(8) +2 = 2.40 +2 = 82 ✓
