Q. Which is the set of numbers greater than 3-3 and less than 44?\newlineChoices:\newline(A){xx3 and x4}\{x | x \leq -3 \text{ and } x \geq 4\} \newline(B){xx3 and x4}\{x | x \geq -3 \text{ and } x \leq 4\} \newline(C){xx<3 and x>4}\{x | x < -3 \text{ and } x > 4\} \newline(D){xx>3 and x<4}\{x | x > -3 \text{ and } x < 4\}
  1. Understand the problem: Understand the problem. We need to find the set of numbers that are greater than 3-3 and also less than 44 at the same time.
  2. Identify inequality signs: Identify the correct inequality signs for the conditions given. For numbers greater than 3-3, we use the > sign. For numbers less than 44, we use the < sign.
  3. Combine conditions in set notation: Combine the two conditions with the correct inequality signs to form the set notation. The set notation should include both conditions: numbers greater than 3-3 and numbers less than 44.
  4. Review and match choices: Review the choices given and find the one that matches our set notation from Step 33. The correct set notation should be \{x | x > -3 \text{ and } x < 4\}.
  5. Match correct set notation: Match the correct set notation to the choices provided. Choice (D) {x | x > -3 \text{ and } x < 4} is the correct answer because it represents all numbers that are greater than 3-3 and less than 44.
