Answer:
[-8,8]
Explanation:
The absolute value sign denotes the distance from 0 on the number line.
So given that A is a positive constant: |A|=A and |-A|=A
so when |x|<=8
we have 2 cases:
x<=8
-x<=8 which is x>=-8
combine these two to get -8<=x<=8 or in interval notation:
x=[-8,8]
hope this helps!
