Best ResponseYou've already chosen the best response.0Note that the xcoordinate of the vertex of y = ax^2 + bx + c is b/(2a), so the xcoordinate of the vertex of y = 2x^2  4x + 1 is: b/(2a) = (4)/[2(2)] = 1. Then, since the axis of symmetry is the vertical line that passes through the vertex, the axis of symmetry is x = 1. I hope this helps!
