AXIS OF SYMMETRY 4

Find the axis of symmetry for F(x) = 9x² + 3x + 8

Solution

a=9, b=3

Axis of symmetry = -b/2a

                                  =  -(3)

                                       2 x 9

                                  =   -3

                                       18

                                  =   -1

                                        6

Hence the axis of symmetry is ^-1/6
