Question

What form do we place a quadratic in to find the Vertex, or "extrema” of a quadratic function?​

Answer 1

The vertex form of the quadratic function, f(x) = a·(x - h)² + k

Explanation:

The general form of a quadratic function is given as follows;

f(x) = a·x² + b·x + c

The vertex form of the quadratic function is f(x) = a·(x - h)² + k

Where;

(h, k) = The coordinates of the vertex of the parabola

h = -b/2·a, k = f(h)
