Which statement about the graphs is true? Graph A Graph A is a valid density curve because the part of 0.25 the graph from 2 to 6 is below the horizontal axis. 0.1875 Graph A is not a valid density curve because the 0.125 part of the graph from 1 to 2 is above the horizontal axis. 0.0625 Graph B is not a valid density curve because part 1 3 4 of the horizontal axis has negative values. -0.625 Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the -0.125 -0.1875 curve is 1.
