how to find the vertex of a graph How to Find the Vertex from the Graph of a Parabola Step 1 Identify if the graph opens up or down If the graph approaches infinity as x gets bigger then the graph opens up If
Steps for Identifying the Vertex of a Quadratic Equation To find the vertex of a quadratic function which is the highest or lowest point on its graph I follow these systematic steps Recognize the quadratic equation s formula which is y ax 2 bx c For standard form y Ax 2 Bx C Look at the coefficient of the x 2 term If A is positive the parabola opens up If A is negative then the parabola opens down For Vertex Form y a x h 2 k The sign of a determines the direction of the parabola If a is positive the parabola opens up

1 Learn Euler s Formula Euler s Formula as it is used in reference to geometry and graphs states that for any polyhedron that does not intersect itself the number of faces plus the number of vertices minus the number of edges will always equal two 2 Written out as an equation the formula looks like F V E 2 Try to graph y x a 1 and then y 2x a 1 and y 1 2 x a 1 you will what I mean about skinny and fat parabola About the vertex the vertex is determined by x h and k The x value that makes x h 0 will be the x coordinate of the vertex K will be the y coordinate of the vertex y 10 x 4 3

Instead of using the formula x b 2a we can convert the standard form f x ax 2 bx c into vertex form f x a x h 2 k by completing the square to find the vertex h k The vertex of a parabola f y ay 2 by c is f b 2a b 2a 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 h k where h b 2a and evaluate y at h to find k Vertex Formula The two vertex formulas to find the vertex is Formula 1 h k b 2a D 4a where D is the denominator
