AXIS OF SYMMETRY 3

Find the axis of symmetry for F(x) = 4x² + 10x + 8

Solution

a=4, b=10

Axis of symmetry = -b/2a

                                  =  -(10)

                                       2 x 4

                                  =   -10

                                          8

                                  =   -5

                                         4

Hence the axis of symmetry is ^-5/4
