How to stretch a parabola

WebIf we start at the vertex (it does not matter where it is on the graph), go over 1 and count how much you go up or down to determine the magnitude. Several examples and for simplicity's sake, keep the vertex at the origin. If I go over one up two, then the equation is y = 2x^2. over 1 up 3 it is y = 3x^2, over 1 down 1, then y = - x^2, over 1 ... WebSep 8, 2024 · You can shift a parabola based on its equation. [11] 1 Shift a parabola upward. Consider the equation y = x2 +1. This shifts the original parabola upward 1 unit. The vertex is now (0, 1) instead of (0, 0). It will retain the exact shape of the original parabola, but every y-coordinate will be shifted upward 1 unit.
