Question
Write the inequation that represent the interval and state whether the interval is bounded or unbounded.
[0, 0.9]
Solution
[0, 0.9]
Here, x takes values between 0 and 0.9, including 0.9 and excluding 0.
∴ The required inequation is 0 < x ≤ 0.9
∴ it is a bounded (semi-right closed) interval.
