WebNov 19, 2024 · y = a (x - h)2 + k . And if the parabola opens horizontally (which can mean the open side of the U faces right or left), you'll use this equation: x = a (y - k)2 + h . Because the example parabola opens vertically, let's use the first equation. Next, substitute the parabola's vertex coordinates (h, k) into the formula you chose in Step 1.
