Q. Which is the set of numbers less than or equal to 3?Choices:(A){x∣x<3}(B){x∣x=3}(C){x∣x≤3}(D){x∣x≥3}
Understand Inequality Sign: Understand the inequality sign needed for the problem. We are looking for numbers that are less than or equal to 3. The inequality sign that represents "less than or equal to" is ≤.
Match with Set Notation: Match the correct inequality sign with the set notation options provided. We need to find the set notation that correctly uses the "≤" sign to represent numbers less than or equal to 3.
Review and Select: Review the choices and select the one that matches our requirement. The correct set notation for numbers less than or equal to 3 is {x∣x≤3}.
Verify Inclusion: Verify that the chosen set notation correctly includes all numbers less than 3 and the number 3 itself. This is important to ensure that the set notation is not only for numbers strictly less than 3, but also includes 3.
