From the graph we see that x takes the values in blue, those values are:
• x > 4,
,
• x < -4.
Now, the function absolute value |x| is equal, by definition, to:
• x if x > 0,
,
• -x if x < 0.
Using the absolute value, we represent the values of the graph with the following inequality:
[tex]4<|x|[/tex]
Answer
[tex]4<|x|[/tex]
