To find the solution set for the inequality |2x - 7| ≤ 11, we can split it into two cases: 2x - 7 ≤ 11 and 2x - 7 ≥ -11.
Case 1: 2x - 7 ≤ 11
Adding 7 to both sides gives 2x ≤ 18
Dividing both sides by 2 gives x ≤ 9
Case 2: 2x - 7 ≥ -11
Adding 7 to both sides gives 2x ≥ -4
Dividing both sides by 2 gives x ≥ -2
Therefore, the solution set for the inequality is -2 ≤ x ≤ 9. Thus, the correct choice is A. The solution is one or more intervals. The solution is [-2, 9]
