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. The graph represents which system of inequalities? A. y ≤ −3x − 1 y ≤ −x − 4 B. y > −3x + 1 y ≤ −x − 4 C. y < 3x − 1 y ≤ −x + 4 D. y ≤ 3x − 1 y ≥ −x + 4
