Did you know?
Web1 Answer. Plug in ( x, y) = ( 18, 13.6) to get 13.6 = a ( 18 − 12) 2 + 16 and then solve for a. You can do this because you know the point ( 18, 13.6) is on the parabola, so it must satisfy the equation. thanks. it seems so obvious, but i didn't think of it - probably because it's a quadratic formula and we started it only today. WebNov 19, 2024 · 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. Since you know the vertex is at (1,2), you'll substitute in h = 1 and k = 2, which gives you the following: y = a (x - 1)2 + 2

WebThe vertex form of a parabola's quadratic equation looks like this: y = a ( x − h) 2 + k. When the equation is reformatted as above, the point (h, k) is the vertex. The a in the vertex form is the same a as in y = ax2 + bx + c; that is, both of the a 's have exactly the same value. The sign on a (plus or minus) tells you whether the quadratic ... WebThe other method to find the vertex of a parabola is as follows: We know that the x-coordinate of a vertex, (i.e) h is -b/2a. Now, substitute the x-coordinate value in the given …
