Question

Dados f(x) = log3 (x + 1), g(x) = 4 + log2 x e h(x) = log2x, determine.

a) h(5)

b) h(50)

c) g(1)

d) f(0)

Answer 1

Resposta:

Basta substituir os valores nas respectivas funções:

a)

$h(5) = log(2 \times 5)$

$h(5) = log(10)$

$h(5) = 1$

b)

$h(50) = log(2 \times 50)$

$h(50) = log(100)$

$h(50) = 2$

c)

$g(1) = 4 + log_{2}(1)$

$g(1) = 4$

d)

$f(0) = log_{3}(0 + 1)$

$f(0) = 0$
