Question Number 179058 by sciencestudent last updated on 24/Oct/22
f(x)=(((x−2)/(x+1)))^(1/3)        Dom_(f(x)) =?
$${f}\left({x}\right)=\sqrt[{\mathrm{3}}]{\frac{{x}−\mathrm{2}}{{x}+\mathrm{1}}}\:\:\:\:\:\:\:{Dom}_{{f}\left({x}\right)} =? \\ $$

x∈R ∧ x+1≠0  x∈R ∧ x≠−1  x∈R−{−1}
$${x}\in\mathbb{R}\:\wedge\:{x}+\mathrm{1}\neq\mathrm{0} \\ $$$${x}\in\mathbb{R}\:\wedge\:{x}\neq−\mathrm{1} \\ $$$${x}\in\mathbb{R}−\left\{−\mathrm{1}\right\} \\ $$
