On a number line, (-∞,2)∪(2,∞) is equivalent to which statement?

Answer and explanation

Correct answer: x≠2

The governing concept is interpreting a union of intervals and an excluded point. The interval (-∞,2) contains every real number less than 2, and (2,∞) contains every real number greater than 2. Their union therefore covers the entire real number line except the single value 2. Because both intervals use a parenthesis at 2, the value 2 is not included. The equivalent statement is x≠2, so option B is correct. Option A identifies only the missing point rather than the shaded solution set. Options C and D include 2 and cover only one side or one half-line, so they cannot represent both portions of the union.
