If the representation of x is from 1 to 5 and only 1 is included, what is the interval?

Answer and explanation

Correct answer: [1, 5)

Interval notation uses a square bracket when an endpoint belongs to the solution set and a round parenthesis when it does not. The statement says that the interval runs from 1 to 5 and only 1 is included. Therefore 1 receives a square bracket, while 5 receives a parenthesis. The resulting interval is [1, 5), meaning 1 ≤ x < 5. Option A excludes both endpoints, option B includes both, and option D excludes 1 but includes 5. Since those endpoint conditions contradict the wording, option C is the only correct answer. The notation and the corresponding inequality express exactly the same set of real numbers.
