what is the graphing form of a quadratic function The graph of a quadratic function is a parabola The general form of a quadratic function is f x ax 2 bx c with real number parameters a b and c and a neq 0 The standard form or vertex form of a quadratic function is f x a x h 2 k with real number parameters a h and k and a neq 0

We will study a step by step procedure to plot the graph of any quadratic function Consider the general quadratic function f x ax 2 bx c First we rearrange it by the method of completion of squares to the following form f x a x b 2a 2 D 4a The term D is the discriminant given by D b 2 4ac To graph a quadratic equation start by solving for h in vertex form or taking b divided by 2 times a in standard form Then define or calculate the value of k and plot the point h k which is the vertex of your parabola
