how to find x intercepts of a quadratic in vertex form From standard form we can find the vertex and either factor or use the Quadratic Formula to find the x intercepts The intercept form of a quadratic equation is y a x p x q where a is the same value as in
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 we can find the x intercepts of the parabola by using the quadratic formula 1st x intercept x b sqrt b 2 4ac 2a 2nd x intercept x b sqrt b 2 4ac 2a

The factored form of quadratic equations is basically the product of the two binomials that led to the quadratic equation This allows you to see the x intercepts of the quadratic x a x b To find the vertex in this form you must take the average of Find the latex y latex intercept of a quadratic function Find the real number latex x latex intercepts or roots of a quadratic function using factoring and the quadratic formula
To find x intercepts of a quadratic function I first set the function equal to zero and solve for x This is because the x intercepts also known as the roots or solutions are the points where the function crosses the x axis which corresponds to a function value of y 0 This video shows how to find the vertex and x intercepts of a quadratic function You will use these to help in graphing the function UrbCon Education merch shop
