Math Problem Statement
Solution
The inequality in the image is:
To solve this inequality, we can break it down as follows:
Step 1: Understanding the absolute value inequality
The absolute value inequality describes the distance of from 0. Specifically:
- means that is at least 1 unit away from 0, in either the positive or negative direction.
- means that is less than 4 units away from 0, in either the positive or negative direction.
Step 2: Solving the inequality
The inequality can be broken into two cases for each part:
This translates to two simultaneous inequalities:
and
For :
- This means or (since the absolute value is greater than or equal to 1).
For :
- This means .
Step 3: Combine the two conditions
Now, we combine the results from the two inequalities:
- gives us or .
- gives us .
Combining these two conditions, we get:
- For the first part , we need , so .
- For the second part , we need .
Final Answer:
The solution to the inequality is:
This is the set of all such that is between -4 and -1 (inclusive of -1) or between 1 and 4 (inclusive of 1, but not 4).
