Please explain why it should notbe -9y instead of -y?

No, it is (0, 14). When you graph the parabola, the y-intercept is (0, 14). Also, when you substitute 0 in the parabola, you get 2(3)^2-4, which is 18-4, which is 14.

It can be seen that there are two negative signs before the 2, meaning that it is actually addition rather than subtraction because a double negative equals a positive. This would mean that it shifts 2 units up rather than down.
