FUNCTIONS - 2




Find the axis of symmetry for F(x) = 8x2 - 64x + 3

Solution

Axis of symmetry = -b/2a

                               =  -(-64)
                                    2 x 8

                               =    64
                                     16

                                =   4

Hence the axis of symmetry is 4
