Graphing vertex form of a quadratic equation
WebFeb 16, 2024 · In this form, the quadratic equation is written as: f (x) = a (x - h) 2 + k where a, h, and k are real numbers and a does not equal zero. Vertex form is so named because h and k directly give you the vertex (central point) of your parabola at the point (h,k). Two vertex form equations are f (x) = 9 (x - 4) 2 + 18 and -3 (x - 5) 2 + 1 WebOct 6, 2024 · If a quadratic function is given in vertex form, it is a simple matter to sketch the parabola represented by the equation. For example, consider the quadratic function …
