4. Consider the inequality | 2| < 3. As needed, reference back to the terminology of Exercise 3 above. A. State the solution to this inequality in interval notation. B. Consider your solution interval from part A. What is the width of the resulting solution interval? What is its midpoint? What is its radius? C. If the original inequality of interest were instead |¤ − 2| ≤ 3, exactly two additional real numbers must be included in your solution interval (as compared to your solution interval from part A). Which two real numbers are included in this case? Explain.
