Question

so da C e da E prfvr​

Answer 1

Resposta:

Explicação passo-a-passo:

c)

$g(\sqrt{2})=-(\sqrt{2})^{2}+5\sqrt{2}+3\\\\g(\sqrt{2})=-2+5\sqrt{2}+3\\\\\boxed{g(\sqrt{2})=5\sqrt{2}+1}$

e)

$g(\frac{2}{3})=-(\dfrac{2}{3})^{2}+5.\dfrac{2}{3}+3\\\\g(\frac{2}{3})=-\dfrac{4}{9}+\dfrac{10}{3}+3\\\\mmc(9,3)=9\\\\g(\frac{2}{3})=\dfrac{-4+30+27}{9}\\\\\boxed{g(\frac{2}{3})=\dfrac{53}{9}}$
