Exercice 13 svp urgent !!

[tex]g(0) = 2 \sqrt{0}+1 = 2\times0+1=0\\\\ g(0,25) = 2 \sqrt{0,25}+1= 2\times0,5+1=2\\\\ g(3) = 2 \sqrt{3}+1\\\\ [/tex]

[tex]g(-9) = 2 \sqrt{-9}+1 => \text{impossible de faire la racine} \text{d'un nombre negatif}\\\\ g(4) = 2 \sqrt{4}+1=2\times2+1=5\\\\ g( \frac{25}{36})=2 \sqrt{ \frac{25}{36} } +1=2\times \frac{5}{6}+1= \frac{8}{3} [/tex]
