The graph of 9) is a translation of the function f(x) = x The vertex of (x) is located 5 units above and 7 units to the nght of the vertex ofc). Which equation represents (x)?
O 900) = (x + 7) +5
O 90x) = (x-7)+5
900) = (x + 5)2 + 7
O 9(c) = (x - 5)2 +7

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.
