How to do this ?? How

Answer 1

|ax - b| > c

The two bars | | is used to indicate the function absolute value.

Remember this definition:

| x | = - x if x < 0 and x if x > 0

So, | x | > c =>

x > c or x > - c

Therefore:

|ax - b| > c => ax - b > c or ax - b > - c

That is the third option of the answer list.
