FUNCTIONS 1

Find the axis of symmetry for F(x) = 6x2 + 10x + 8

Solution

a=6, b=10

Axis of symmetry = -b/2a

                               =  -(10)
                                    2 x 6

                               =    -10
                                      12


Hence the axis of symmetry is -5/6

TRY THIS…………………
