graph A Graph shows upward parabola and a line plotted on a coordinate plane. The parabola has vertex at (minus 2, minus 1) with left slope at B (minus 3, 0) and right slope at (minus 1, 0). The line goes through (minus 3, 0) and B (1, 8). graph B Graph shows upward parabola and a line plotted on a coordinate plane. The parabola has vertex at (2, minus 1) with left slope at A (minus 1, 8) and right slope at (5, 8). The line goes through (minus 1, 8) and B (3, 0). graph C Graph shows upward parabola and a line plotted on a coordinate plane. The parabola has vertex at (2, minus 1) with left slope at A (minus 3, 0) and right slope at (minus 1, 0). The line goes through (minus 3, 0) and B (0, 6). graph D Graph shows upward parabola and a line plotted on a coordinate plane. The parabola has vertex at (2, minus 1) in quadrant 4, with left slope at A(1, 0), (0, 3), (minus 1, 8), and right slope at (3, 0), (5, 8). A line goes through (3, 0) and B(0, 6).
