What are different types of statistical programs

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

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.
