Which оf the fоllоwing points represents а vаlid solution to the constrаints represented by the inequalities shown in the graph? The x-axis spans from negative 5 to 5, and the y-axis spans from below 0 to above 5. Both axes have a scale of 5 in increments of 1. A solid black inverted V-shaped function peak at (negative 1, 5). It opens downward with a y-intercept of (0, 4), an x-intercept of 4, 0), while enclosing a gray-shaded region below it. A dashed purple V-shaped function has a sharp vertex at (2, negative 1). It opens upward, with x-intercepts of (1, 0) and (3, 0), y-intercept of (0, 1), while enclosing a purple-shaded region above it. The two shaded areas overlap with intersection points (negative 2.5, 3.5) and (3.5, 0.5). The overlap forms a dark purple rectangular region at the center of the graph, spanning the first, second, and slight of the fourth quadrants.
