AXIS OF SYMMETRY 1

Find the axis of symmetry for F(x) = 6x² + 48x + 8

Solution

a=6, b=48

Axis of symmetry = -b/2a

                                  =  -(48)

                                       2 x 6

                                 =    -48

                                         12

                                 =   -4

                                       

Hence the axis of symmetry is ^-10/3
