This graph represents the solution to $\displaystyle{x}\ge-{4}\usepackage{cmbright}\Huge\$ or $\displaystyle{x}\le-{2}\usepackage{cmbright}\Huge\$ , which includes all real numbers. You may have thought you had to reverse the inequality symbols in each inequality. Remember that you only reverse the inequality symbols if you divide or multiply both sides of the inequality by a negative number. The correct answer is the graph with the closed circles at $\displaystyle-{4}\usepackage{cmbright}\Huge\$ and $\displaystyle-{2}\usepackage{cmbright}\Huge\$ , the arrow going left from $\displaystyle-{4}\usepackage{cmbright}\Huge\$ , and the arrow going right from $\displaystyle-{2}\usepackage{cmbright}\Huge\$ .
