AXIS OF SYMMETRY 2

Find the axis of symmetry for F(x) = 30x² + 4x + 8

Solution

a=30, b=4

Axis of symmetry = -b/2a

                                   =  -(4)

                                       2 x 30

                                   =    -4

                                         60

                                    =   -1

                                          15

Hence the axis of symmetry is ^-1/15
