Find the solution of the following in equations by graphical method:|x|≤ 3

Question

Philoid · Accepted Answer

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

and x = – 3, two lines drawn parallel to x – axis.

Now,

|0|< 3, satisfies the inequality hence

|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.
