If 2 ≤ x ≤ 6, which of the following is a solution?

Answer and explanation

Correct answer: x = 6

The governing idea is testing membership in a closed interval. The statement 2 ≤ x ≤ 6 means that x may be any real number from 2 through 6, and both endpoints are included because the symbols are ‘less than or equal to.’ Test the choices directly: x = 6 satisfies 2 ≤ 6 and 6 ≤ 6, so it belongs to the solution set. The value 7 is greater than the upper limit, while 1 and 0 are less than the lower limit. Therefore, option A is the only valid solution. A strict inequality would exclude an endpoint, but that is not the case here.
