Image 2: a segment from -4 to 4 with the endpoints excluded (with empty circles).
Step-by-step explanation:
|x| < 4 means "the distance from x to 0 is less than 4". That means that any number bigger than -4 and smaller than 4 matches the inequality from the question.
Side note: Please start analyzing the absolute values as "distance from 0" and you'll be able to solve those questions yourself with less effort.
