Converting Standard Form of Quadratic Function Into Vertex FormĪ quadratic function f(x) = ax 2 + bx + c can be easily converted into the vertex form f(x) = a (x - h) 2 + k by using the values h = -b/2a and k = f(-b/2a). Let us see how to convert the standard form into each vertex form and intercept form. We can easily convert vertex form or intercept form into standard form by just simplifying the algebraic expressions. We can always convert one form to the other form. If a If a > 0, then the parabola opens upward.The parabola opens upwards or downwards as per the value of 'a' varies: Intercept form: f(x) = a(x - p)(x - q), where a ≠ 0 and (p, 0) and (q, 0) are the x-intercepts of the parabola representing the quadratic function.Vertex form: f(x) = a(x - h) 2 + k, where a ≠ 0 and (h, k) is the vertex of the parabola representing the quadratic function.Standard form: f(x) = ax 2 + bx + c, where a ≠ 0.Here are the general forms of each of them: 1.Ī quadratic function can be in different forms: standard form, vertex form, and intercept form. We will also solve examples based on the concept for a better understanding. You will get to learn about the graphs of quadratic functions, quadratic functions formulas, and other interesting facts about the topic. In this article, we will explore the world of quadratic functions in math. Did you know that when a rocket is launched, its path is described by quadratic function? In other words, a quadratic function is a “polynomial function of degree 2.” There are many scenarios where quadratic functions are used. ![]() The word "Quadratic" is derived from the word "Quad" which means square. Depending on the coefficient of the highest degree, the direction of the curve is decided. ![]() Graphically, they are represented by a parabola. Quadratic functions are used in different fields of engineering and science to obtain values of different parameters.
