Q. What does the set {xx>2 and x5}\{x | x > -2 \text{ and } x \leq 5\} represent?\newlineChoices:\newline(A)all numbers less than 2-2 and greater than 55 \newline(B)all numbers greater than 2-2 and less than or equal to 55 \newline(C)all numbers less than 2-2 and greater than or equal to 55 \newline(D)all numbers greater than or equal to 2-2 and less than or equal to 55
  1. Understand set notation: Understand the set notation. The set {x | x > -2 \text{ and } x \leq 5} uses the inequality symbols '>' and '\leq' to describe the range of numbers that xx can be. The '>' symbol means 'greater than' and the '\leq' symbol means 'less than or equal to'.
  2. Interpret first condition: Interpret the first condition x > -2. This means that xx must be greater than 2-2, which includes all numbers that are just above 2-2 but not 2-2 itself.
  3. Interpret second condition: Interpret the second condition x5x \leq 5. This means that xx must be less than or equal to 55, which includes all numbers up to and including 55.
  4. Combine conditions: Combine both conditions. Since xx must satisfy both conditions simultaneously, xx must be a number that is greater than 2-2 and at the same time less than or equal to 55. This means xx can be any number between 2-2 (not including 2-2) and 55 (including 55).
  5. Match to given choices: Match the combined condition to the given choices. The set of numbers that are greater than 2-2 and less than or equal to 55 corresponds to choice (B) all numbers greater than 2-2 and less than or equal to 55.
