Hоw mаny sоlutiоns does the system represented by the pаrаbola and absolute value graph have? The x-axis spans from below zero to just above 6, and the y-axis spans from below negative 2 to 6. Both axes have a scale of 2 in increments of 0.5. The red parabola opens upward, with its vertex at approximately (2, negative 1), y-intercept at (0, 3), and x-intercepts at (1, 0) and (3, 0). The green V-shaped function consists of two linear segments meeting at a sharp vertex around (3, 1), extending in opposite directions with negative and positive slopes respectively. The left segment with negative slope passes through the point (0, 4) and the right segment with positive slope passes through the point (6, 4). The two graphs intersect at two points. The first point is roughly located halfway between x-values of 0 and negative 0.5 and y-values of 4 and 4.5. The second point is roughly halfway between x-values of 3.5 and 3.75 and y-values of 1.5 and 1.75.
