Question

dada a função exponencial f(x)=8ˣ , determine:

a)f(1)= ㅤㅤㅤㅤㅤㅤb)f(2)=ㅤㅤㅤㅤㅤㅤc)f(1/3)=ㅤㅤㅤㅤㅤㅤd)f(-1/3)=ㅤㅤㅤㅤ
​

Answer 1

Resposta:

a) $f(x) = 8^{1}$ = 8

b) $f(x) = 8^{2}$ = 16

c) $f(x) = 8^{\frac{1}{3} }$ = $\sqrt[3]{8}$ = 2

d) $f(x) = 8^{-\frac{1}{3} }$ = $\frac{1}{\sqrt[3]{8} }$ = $\frac{1}{2}$
