Set the derivative of y equal to 0 This will give you the x for the minimum The perpendicular line through that x is the axis of symmetry y = 2x^2 4x 6 y' = 4x 4 For y' = 0 4x 4 = 0 → x = 1, which is also the equation of the axis of syX = 4 (4,2);Solution for Graph the parabola and give its vertex, axis of symmetry, xintercepts, and yintercept y = x2 4x 5
