The graph of y x3 is translated so that the point (1. 1) is moved to (1, 4). what is the equation of the new graph?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
