Q. Which is the set of numbers greater than or equal to −5 and less than or equal to −2?Choices:(A) {x∣x<−5 and x>−2}(B) {x∣x≥−5 or x<−2}(C) {x∣x≤−5 and x≥−2}(D) {x∣x≥−5 and x≤−2}
Understand the problem: Understand the problem. We need to find the set of numbers that are greater than or equal to −5 and at the same time less than or equal to −2.
Identify inequality signs: Identify the correct inequality signs for the conditions given. For "greater than or equal to −5", the inequality sign is ≥. For "less than or equal to −2", the inequality sign is ≤.
Combine conditions logically: Combine the two conditions using the correct logical connector. Since a number has to satisfy both conditions at the same time, we use "and" to combine them.
Translate into set notation: Translate the combined conditions into set notation. The correct set notation for numbers that are greater than or equal to −5 and less than or equal to −2 is {x∣x≥−5 and x≤−2}.
Match with given choices: Match the correct set notation with the given choices. The correct choice is (D){x∣x≥−5 and x≤−2}.
