Which Of The Following Is The Graph Of The Quadratic Function Y X2 4x 4 Brainly Com The function is f(x) = y = 2x 2 4x 3 The standard form of parabola equation is f(x) = ax 2 bx c Step 1 Find the axis of symmetry Formula for the equation of the axis of symmetry x = b/2a Substitute the values of b = 4 and a = 2 in the formula, x = b/2a x = ( y 2 4 = x 2 4x 4 Now that the right hand side is a perfect square trinomial, factor it y 2 = (x 2) (x 2) y 2 = (x 2) 2 Subtract 2 from both sides y = (x 2) 2 2 When the equation is in this form, we can see that this is the graph of y = x 2 shifted to the right 2 units and shifted down 2 units The vertex is at (2, 2) Y=x/2+1/4 graph
