2, 5, 2, 5
Work Step by Step
When an interval has a square bracket next to a number, it includes that number. 2 has a square bracket next to it, and 5 doesn't. This means that the interval includes 2, but doesn't include 5. The first number in an interval indicates the starting point, and the last number indicates the end point. Therefore, the interval indicates the set of real numbers from 2 to 5, including 2.
