3 ≤ |x| ≤ 4
I honestly have no idea how to begin. I need an interval notation set.
Do I write the equations each having (-) sign on one number? then solve?

dumbcow · Answer

algebraically, whenever you have absolute value split it into 2 cases
$$|x| \ge 3$$
$$\rightarrow x \ge 3 .... x \le -3$$

3 ≤ |x| ≤ 4
So...
x≥3....x≤−3
X≤4....x≥-4
so...


the answer would be [-4,-3] u [3,4]?
