Which trаnsfоrmаtiоns tо аre represented in the graph? "The x-axis spans from negative 10 to 10, and the y-axis spans from negative 5 to just above 15. Both axes have a scale of 5 in increments of 1. The purple V-shaped function consists of two linear segments meeting at a sharp vertex at the coordinate (negative 2, 1). The left segment is in the second quadrant with a negative slope, passing through the point (negative 5, 13). The right segment spans the second and the first quadrants, with a positive slope, passing through the y-axis at (0, 9). The function is symmetric around the vertical line x= negative two and extends out of view in both directions. "
