Triangle XYZ is reflected across the x-axis to produce triangle X'Y'Z'. Then triangle X'Y'Z' is rotated 90° counterclockwise about the origin to create triangle X''Y''Z''. If triangle X''Y''Z'' has vertices X''(4, 0), Y''(2, –1), and Z''(2, 1), what are the coordinates of the vertices of triangle XYZ
