The axis of symmetry for the function f(x) = 2x2 4x 1 is the line x = 1 Where is the vertex of the function located? The vertex form of a quadratic function is given by y = a(x − h)2 k, where (h,k) is the vertex of the parabola We can use the process of Completing the Square to get this into the Vertex Form y = x2 − 4x 2 → y −2 = x2 − 4x (Transposed 2 to the Left Hand Side) Now we ADD 4 from each side to complete the square → y −2 4 = x2 − 4x 22Given y= 8x^2 4x 3 We need to find the vertex We know that a= 8 b= 4 c = 3 Let V be the vertex such that V (xv, yv) xv = b/ 2a ==> 4/2*8 = 4/16 = 1/4

Answer (1 of 3) What is the vertex of the parabola y = x^2 10x 2? The xcoordinate of the vertex is halfway between the xintercepts, so can be found by averaging their values vertex xcoordinate = (1 5)/2 = 2 The ycoordinate of the vertex is the value of y for that value of x y = (2 5)(2 1) = (3)(3) = 9 filling x=2 into the factored equation The vertex is (x, y) = (2, 9) _____Y = a x 2 b x c But the equation for a parabola can also be written in "vertex form" In this equation, the vertex of the parabola is the point ( h, k) You can see how this relates to the standard equation by multiplying it out y = a ( x − h) ( x − h) k y = a x 2 − 2 a h x a h 2 k This means that in the standard form, y
