Q. What does the set {x∣x≥−3 and x≤7} represent?Choices:(A)all numbers greater than or equal to −3 and greater than 7(B)all numbers greater than or equal to −3 and less than 7(C)all numbers greater than or equal to −3 and less than or equal to 7(D)all numbers less than or equal to −3 and greater than or equal to 7
Understand Set Notation: Understand the set notation and the logical connectors.The set x∣x≥−3 and x≤7 uses the logical connector "and," which means that both conditions must be satisfied simultaneously for any number x to be included in the set.
Interpret First Condition: Interpret the first condition x≥−3. This condition means that the set includes all numbers that are greater than or equal to −3.
Interpret Second Condition: Interpret the second condition x≤7. This condition means that the set includes all numbers that are less than or equal to 7.
Combine Conditions: Combine both conditions using the "and" connector.Since we are using "and," we are looking for numbers that satisfy both conditions at the same time. This means we are looking for all numbers that are between −3 and 7, inclusive of both −3 and 7.
Match Combined Conditions: Match the combined conditions to the given choices.The set of numbers that are greater than or equal to −3 and less than or equal to 7 is correctly represented by choice (C).
