How to find the domain of \[f(x)=\sqrt{\frac{8-x^3}{7x}}\]

Answer 1

Since we are dealing with Real numbers here, the stuff under the square root must be greater than or equal to 0:\[\bf \frac{ 8-x^3 }{ 7x }\ge0\] Now find the intervals in which the rational function is greater than or equal to 0. Can you do that?
