Question

Considerando a função exponencial y = (1/2) x como ser o grafico

Answer 1

$~~~x~~~~~~~y=\left( \dfrac{1}{2}\right)^x\\ \boxed{-2}~~~~~~~y=(2^{-1})^{-2}~\Rightarrow y=2^2=\boxed{4}\\ \boxed{-1}~~~~~~~y=(2^{-1})^{-1}~\Rightarrow y=2^1=\boxed{2}\\ ~~~~\boxed{0}~~~~~~~y=(2^{-1})^0~~\Rightarrow y=2^0=\boxed{1}\\ ~~~~\boxed{1}~~~~~~~y=(2^{-1})^1~~\Rightarrow y=2^{-1}= \boxed{\dfrac{1}{2}}\\\\ ~~~~\boxed{2}~~~~~~~y=(2^{-1})^2~~\Rightarrow y=2^{-2}= \boxed{\dfrac{1}{4}}$
