2.5 <= x <= 3.5

Apply this equation and you will get the answer

8=D(0)^8

>>722306651 damn :'c

>>722306640
No, you seem young to have gotten this wrong. You have many years ahead

>>722306651
You mean -2.5 <= x <= 3.5, right?

Are you in some sort of developmental learning math?
Not that'd I'd expect sci standards here, where you would have been laughed at before getting any responses, but this is like, 5th grade stuff.

>|x-1/2| = +/- (x-1/2) <= 3
Take the positive value
>x<=7/2
Now the negative
>-(x-1/2)=-x+1/2<=3
>-x<=5/2
>-5/2<=3
So
>-5/2 <= x <= 7/2
