$y\in(\infty;-4]\cup[4;\infty)$ To graph the solution set, put to square brackets at the points -4 and 4. The set is the space to the left of -4 and to the right of 4.

Work Step by Step

The absolute value of y is larger than or equal to 4, so the value of y is either larger than 4 or smaller than -4. The soltuion set is any number whose distance to 0 is larger than or equal to 4.
