$(-\infty, -4] \cup [1, +\infty)$
Graph each inequality. (refer to the attached image below) The conjunction used is OR, which means that the solution set contains the combined elements of the two inequalities. $x \le -4$ includes all the numbers to the left of -4, including -4 itself $\\x \ge 1$ includes all the numbers to the right of 1, including 1 itself. Combining the elements of these two inequalities gives the solution set: $(-\infty,-4] \cup [1, +\infty)$
