Math Problem Statement
Solution
We are asked to solve the inequality and give the solution set using interval notation.
Step-by-step solution:
-
Isolate the absolute value: The inequality becomes:
-
Solve the absolute value inequality: For , the solution is or .
Therefore:
-
Solve both parts:
- For :
- For :
-
Solution in interval notation: The solution set is or , which can be written in interval notation as:
Thus, the correct choice is A and the solution set is .
