Practice problem
How do you express the compound inequality x≥3x\ge3x≥3 or x≤−3x\le-3x≤−3 in interval notation?
(−∞,3]∪[−3,∞)(-\infty, 3]\cup[-3,\infty)(−∞,3]∪[−3,∞)
(−∞,−3)∪(3,∞)(-\infty, -3)\cup(3,\infty)(−∞,−3)∪(3,∞)
(−3,3)(-3, 3)(−3,3)
(−∞,−3]∪[3,∞)(-\infty, -3]\cup[3,\infty)(−∞,−3]∪[3,∞)
Type a concept, like “slope” or “photosynthesis”.
