Q. What interval does this inequality represent?−1≤x≤4Choices:(A)(−1,4)(B)(−1,4](C)[−1,4](D)[−1,4)
Identify Endpoints: Identify the endpoints of the interval for the inequality −1≤x≤4. The endpoints are −1 and 4.
Check Inclusion: Check whether the endpoints are included in the interval. In the inequality −1≤x≤4, both −1 and 4 are included because of the "less than or equal to" signs (≤).
Determine Interval: Determine the interval that the inequality −1≤x≤4 represents. Since both endpoints are included, the interval is written with square brackets, indicating that −1 and 4 are part of the interval. Therefore, the interval is [−1,4].
