The equation of a parabola is of the form f x ax 2 bx c where a b and c are con The vertex form of a quadratic function is given by f x a x h 2 k where h k is the vertex of the parabola Remember the vertex is the turning point
We know that a quadratic equation will be in the form y ax 2 bx c Our job is to find the values of a b and c after first observing the graph Sometimes it is easy to spot the points where the curve passes through but often we need to estimate the points Let s start with the simplest case Learn how to graph any quadratic function that is given in vertex form Here Sal graphs y 2 x 2 5 Created by Sal Khan

Finding the vertex of the quadratic by using the equation x b 2a and then substituting that answer for y in the orginal equation Then substitute the vertex into the vertex form equation y a x h 2 k a will stay the same h is x and k is y In this article we explain how to find a quadratic function if we know the vertex and a point of it We will see solved examples step by step Enter now to learn
The vertex of the graph of a quadratic function is the highest or lowest possible output for that function If you re looking at a graph the vertex would be the highest or lowest point on the parabola The easiest way to A quadratic function can be in different forms standard form vertex form and intercept form Here are the general forms of each of them Standard form f x ax 2 bx c where a 0 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
