Lesson 1.8: Absolute Value Inequalities

Question 1

Compare the process of solving |x – 1| + 1 15.

Revolt · Accepted Answer

Both absolute values would need to be isolated first. You would need to write a compound inequality for each. Both compound inequalities would compare x – 1 to –15 and 15. The inequality with “ ” would use an “or” statement.
