AXIS OF SYMMETRY 2

Find the axis of symmetry for F(x) = 6x² + 20x + 8

Solution

a=6, b=10

Axis of symmetry = -b/2a

                               =  -(20)

                                    2 x 6

                               =    -20

                                      12

Hence the axis of symmetry is ^-5/3
