So we have a number line.
00:04
And in this number line, we have the point negative two that has an open circle, and then it goes to the left.
00:15
And then we have the number four with an open circle to the right.
00:23
And we want to express the subset with absolute value inequalities.
00:31
And so this would be an interoperable.
00:40
Notation will be from negative infinity to negative two not included, or four not included to infinity, or x is less than, strictly less than negative two, or x is greater than four.
01:06
But we want to express this as an absolute value inequality.
01:18
And so we want the absolute value of, let's say if we center this, it would be at three, or one.
01:31
So then there would be three units between it...
