Findtheequationoftheaxisofsymmetryfortheparabola
y =



x^2 - 6x + 1/4

Answer 1

The coefficients of this quadratic are {1, -6, 1/4}.

The formula for the x-coordinate of the vertex, which is also the formula for the axis of symmetry, is

                                                              -(-6)      6
x = -b/(2a), which here equals     x = --------- = ---- = 3 , or x = 3 (answer)
                                                            2(1)         2
