The solution of the inequality `(|x+2|-|x|)/(sqrt(8-x^(3))) ge 0` isA. `[-1,2]`B. `[1,2]`C. `[-1,1]`D. `[0,3sqrt(4))`

The solution of the inequality `(|x+2|-|x|)/(sqrt(8-x^(3))) ge 0` isA.

1.	The solution of the inequality `(\|x+2\|-\|x\|)/(sqrt(8-x^(3))) ge 0` isA. `[-1,2]`B. `[1,2]`C. `[-1,1]`D. `[0,3sqrt(4))`
Answer» Correct Answer - A `(a)` `(\|x+2\|-\|x\|)/(sqrt(8-x^(3))) ge 0` We must have `8-x^(3) gt 0` `implies x^(3) lt 8 implies x lt 2` Also `\|x+2\|-\|x\| ge 0` `implies \|x+2\| ge \|x\|implies (x+2)^(2)-x^(2) ge 0 implies 2(x+1) ge 0` `implies x ge -1` So `x in [-1,2)`

The solution of the inequality `(|x+2|-|x|)/(sqrt(8-x^(3))) ge 0` isA. `[-1,2]`B. `[1,2]`C. `[-1,1]`D. `[0,3sqrt(4))`
