Q8 of 26 Page 60

Shade the solution set of the inequation |x|≤ 3.

To find the solution set for |x|≤ 3 graphically, we first draw x = 3


and x = – 3, two lines drawn parallel to x – axis. |x|≤ 3 is represented as a shaded region between x = 3 and x = – 3, including all the points lying on the lines x = 3 and x = – 3.
