how to find the vertex a parabola Sal rewrites the equation y 5x 2 20x 15 in vertex form by completing the square in order to identify the vertex of the corresponding parabola Created by Sal Khan and Monterey Institute for Technology and Education
Finding Vertex from Standard Form The x coordinate of the vertex can be found by the formula b 2a and to get the y value of the vertex just substitute b 2a into the the equqation as shown in the diagram and example below To find the vertex of a parabola represented by a quadratic function in f x ax 2 bx c form Step 01 Identify the values of the coefficients a and b Step 02 Use the formula for the vertex of a parabola x b 2a to find the x coordinate value of the vertex point

If you wanted a quick and dirty way to figure out a vertex there is a formula that you can derive it actually doing this exact same process we just did but the formula for the vertex or the x value of the vertex or the axis of symmetry is x is equal to negative b over 2a The vertex formula helps to find the vertex coordinates of a parabola The standard form of a parabola is y ax 2 bx c The vertex form of the parabola y a x h 2 k There are two ways in which we can determine the vertex h k They are h k b 2a D 4a where D discriminant b 2 4ac
The parabola equation in vertex form The standard form of a quadratic equation is y ax bx c You can use this vertex calculator to transform that equation into the vertex form which allows you to find the important points of the parabola 10 years ago y a x h 2 k is the vertex form equation Now expand the square and simplify You should get y a x 2 2hx h 2 k Multiply by the coefficient of a and get y ax 2 2ahx ah 2 k This is standard form of a quadratic equation with the normal a b and c in ax 2 bx c equaling a 2ah and ah 2 k respectively
