Question
Sketch the graph which represents the solution set for the following inequation.
|x| < 4
Advertisements
Solution
|x| < 4 ⇒ − 4 < x < 4
Here, x takes all real values between – 4 and 4.
∴ Solution set represents bounded (open) interval (– 4, 4)
∴ the required graph of the solution set is as follows:
