And if I focus on the vertex of f, it looks like if I shift that to the right by three, and then if I were to shift that down by four, at least our vertices would overlap. Mathematics 101science com. Think about the behavior that we want, right over here, at x equals three. is right over here. 0 and negative 1, it will be a broad-opening And you can validate that at other points. The reason the graph shifts up instead of down when you subtract a number from y is because (if you think about it) subtracting from y is the same as adding that number to the opposite side of the equation which results in a.
