Math Problem Statement
solve the inequality involving absolute value. |x-2|+4>=11
Solution
We are given the inequality involving absolute value:
Step 1: Isolate the absolute value expression.
Subtract 4 from both sides:
Step 2: Solve the inequality for the absolute value.
The expression means that the distance between and 2 is at least 7. This gives two cases to consider:
Case 1:
Solve for :
Case 2:
Solve for :
Step 3: Combine the solutions.
The solution is:
In interval notation, the solution is:

- How do we solve inequalities involving more complex absolute value functions?
- What happens if the inequality sign is strict (i.e., instead of )?
- How do we graph the solution to an absolute value inequality?
- How do absolute value inequalities compare to quadratic inequalities?
- What is the geometric interpretation of absolute value inequalities?
Tip: Always check both cases when solving absolute value inequalities, as they represent the two possible directions from the central point.
