This one isn't particularly difficult. Were u suppose to give us this bit of info: (-8 to 4).

Anyway. E. |x+2|---> x+2 ≤6 ---> x ≤4

|x+2| ---> x+2>=-6 x>=-8 so -8 ≤x ≤4

Note that the centre of the interval is -2, and the endpoints are 6 units from the centre- Remember that |x-y| is the distance between x and y

Thus |x-(-2)| ≤ 6
