In the graph, the area below f(x) is shaded and labeled A, the area below g(x) is shaded and labeled B, and the area where f(x) and g(x) have shading in common is labeled AB. Graph of two intersecting lines. One line g of x is solid and goes through the points 0, 2, negative 2, 4 and is shaded in below the line. The other line f of x is solid, and goes through the points 0, 2, 2, 0 and is shaded in below the line. The graph represents which system of inequalities?
