How do you find k in vertex form
WebOct 6, 2024 · The vertex (h, k) is located at h = – b 2a, k = f(h) = f(− b 2a). HOWTO: Write a quadratic function in a general form Given a graph of a quadratic function, write the equation of the function in general form. Identify the horizontal shift of the parabola; this value is h. Identify the vertical shift of the parabola; this value is k. Weby = a(x-h)^2 + k is the vertex form equation. Now expand the square and simplify. You should get y = a(x^2 -2hx + h^2) + k. Multiply by the coefficient of a and get y = ax^2 -2ahx …
