Work Step by Step
The center of the hyperbola is (0,0). The four corners of the box are (6,6), (-6,6), (6,-6) and (-6,-6). Draw a dotted box through these points. Then draw two dotted lines through the corners. The vertices of the hyperbola are (6,0) and (-6,0), so plot those points and draw two smooth curves nearing the two asymptotes without touching them.
