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

TRY THIS...............


Find the axis of symmetry for F(x) = 2x2 + 24x + 8.
