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!
