how to find the vertex of a parabola The vertex of a parabola is a point at which the parabola makes its sharpest turn The vertex of f x ax 2 bx c is given by b 2a f b 2a Learn how to find vertex of a parabola from different forms like standard form vertex form and intercept form
This algebra 2 video tutorial explains how to find the vertex of a parabola given a quadratic equation in standard form vertex form and factored form 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

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 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
In order to find the vertex of a parabola given its equation in standard form eq f x ax 2 bx c eq calculate the ordered pair h k 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
