The graph shown represents the set of x in which x is either less than or equal to $\displaystyle-{2}\usepackage{cmbright}\Huge\$ or x is greater than 4. Solving the first inequality for x gives you $\displaystyle{x}\le-{2}\usepackage{cmbright}\Huge\$ . Solving the second inequality gives you $\displaystyle{x}>{4}\usepackage{cmbright}\Huge\$ . This solution matches the graph.
