Найдите ОДЗ функции

Решите задачу:

$y= \sqrt[6]{x^2-x-1}-\frac{\sqrt[3]{3x-1}}{\sqrt[4]{-x-1}} \\\\ODZ:\quad \left \{ {{x^2-x-1 \geq 0} \atop {-x-1\ \textgreater \ 0}} \right. \; \; \left \{ {{(x-\frac{1-\sqrt5}{2})(x-\frac{1+\sqrt5}{2}) \geq 0} \atop {x\ \textless \ -1}} \right. \\\\\\ \left \{ {{x\in (-\infty ,\; \frac{1-\sqrt5}{2}}]\cup [\frac{1+\sqrt5}{2},+\infty ) } \atop {x\in (-\infty ,-1)}} \right. \; \; \Rightarrow \; \; x\in (-\infty ,-1)\\\\\\ \frac{1-\sqrt5}{2} \approx -0,6\; ,\; \; \frac{1+\sqrt5}{2}\approx 1,6$
