write and equation for g(x) in terms of f(x) after the transformation of a horizontal stretch by a factor of 1/6, and a vertical translation of 4 units down. f(x)=sqrt(x)

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.
