AXIS OF SYMMETRY 1


Find the axis of symmetry for F(x) = 7x2 - 50x + 7

Solution

a=7, b=-4

Axis of symmetry = -b/2a

                              =  -(-50)
                                  2 x 7

                              =    50
                                   14

                              =     25
                                     7


Hence the axis of symmetry is 25/7
