The integer k for which the inequality x 2

WebExample: x ≤ 2 or x >3. On the number line it looks like this: And interval notation looks like this: (-∞, 2] U (3, +∞) We used a "U" to mean Union (the joining together of two sets). Note: be careful with inequalities like that one. Don't try to join it into one inequality: 2 ≥ x > 3 wrong! that doesn't make sense (you can't be less than 2 WebApr 1, 2015 · 1 Answer. Alan P.
