Answer to Problem 74PPE
The absolute value inequality that represents all real numbers at least 2 units from -1 is
Explanation of Solution
Given information:
The requiredset of numbers is: all real numbers at least 2 units from -1.
Concept used:
The absolute value inequality
Calculations:
The given set is: “all real numbers at least 2 units from -1.”
Areal numbers x at least 2 units from -1 is the number equal or less than -1-2 and equal or greater than -1+2, i.e. number x is
The representation on real line is shown in Figure-1 here.
Thus, the absolute value inequality that represents all real numbers at least 2 units from -1 is
Conclusion:
The absolute value inequality that represents all real numbers at least 2 units from -1 is
