FUNCTIONS B3

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

Solution

a=3, b=-64

Axis of symmetry = -b/2a

                               =  -(-64)

                                    2 x 3

                               =    64

                                      6

                               =    32

                                      3

  

Hence the axis of symmetry is ³²/3
