AXIS OF SYMMETRY 1

Find the axis of symmetry for F(x) = 10x² + 16x + 8

Solution

a=10, b=16

Axis of symmetry = -b/2a

                                 =  -(16)

                                   2 x 10

                                =    -16

                                       20

                                =   -4

                                     5

Hence the axis of symmetry is ^-4/5
