WebAug 25, 2024 · How do you write vertex and point in vertex form? Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola. The vertex of a parabola is the point at the top or bottom of the parabola. ‘h’ is -6, the first coordinate in the vertex. ‘k’ is -4, the second coordinate in the vertex. WebIf the quadratic is written in the form y = a(x − h) 2 + k, then the vertex is the point (h, k). This makes sense, if you think about it. The squared part of y = a(x − h) 2 + k is always positive (for a right-side-up parabola), unless it's zero. So you'll always have that fixed value k, and then you'll always be adding something to it to ...
