Answer:
1. x=-4, x=4
2. -x<4, x<0
3. (*-8, -4), (4, *8)
4. -x≤4, x<0
c
a
d
b
According to the number line,
|x| = 4 means an absolute value of 4 or -4 is 4.
|x| < 4 means an absolute value of 4 or -4 is less than 4.
|x| > 4 means an absolute value of 4 or -4 is greater than 4.
|x| ≤ 4 means an absolute value of 4 or -4 is no more than 4.
