Question

o dominio da função real definida por y=.......

Answer 1

$\Large\boxed{\begin{array}{l}\sf\ell og_{\frac{1}{2}}x+3\geqslant0\\\\\sf C\cdot E: x+3>0\\\sf x>-3.\\\sf \ell og_{\frac{1}{2}}x+3\geqslant\ell og_{\frac{1}{2}}1\\\sf x+3\leqslant1\\\sf x\leqslant1-3\\\sf x\leqslant-2\\\sf combinando~os~intervalos~temos\\\sf Df(x)=\{x\in\mathbb{R}/-3<x\leqslant-2\}\\\sf o~gabarito~do~anexo~est\acute a~incorreto.\end{array}}$
