Answer:

x = 3

Step-by-step explanation:

The formula for the axis of symmetry is x = -b/[2a].  Here, a = -3 and b = 18.

             

                                                            -18

Thus, the axis of symmetry is x = - ------------ = 3, or x = 3

                                                            2[-3]
