1.	How to solve for x, if \|x-1\| ≥ 3?(a) (-∞, -2) ∪ (4, ∞)(b) (-∞, -2] ∪ [4, ∞)(c) (0, -2] ∪ (4, 0)(d) (-∞, ∞) – {-2, 4}The question was posed to me during a job interview.The question is from Sets and their Representations in division Sets of Mathematics – Class 11
Answer» RIGHT choice is (b) (-∞, -2] ∪ [4, ∞) EASY explanation: Given, \|x-1\| ≥ 3 = x-1 < -3 or x – 1 ≥ 3 = x ≤ -2 or x ≥ 4 Hence, x c (-∞, -2] ∪ [4, ∞).
