WebFree Parabola calculator - Calculate parabola foci, vertices, axis and directrix step-by-step WebApr 10, 2024 · For such parabolas, the standard form equation is (y - k)² = 4p x–hx–hx – h T. Here, the focus point is provided by (h + p, k) These open on the x-axis, and thus the p-value is then added to the x value of our vertex. That said, these parabolas are all the more same, just that the x and y are swapped. The 4p in the standard form of the ...
