Answer

$x\lt-2$ or $x\geq1$

Work Step by Step

Two lines on the same graph represent a compound inequality that includes "or". An open circles at the left endpoint means -2 is not part of the solution set, so the inequality operator does not include "or equal to". A solid circles at the right endpoint means 1 is part of the solution set, so the inequality operator includes "or equal to".
