Answer:

  x = 6

Step-by-step explanation:

The line of symmetry for the parabola written in the form y=ax²+bx+c is given by the equation x=-b/(2a).

__

Comparing your equation to the above form, we see ...

  • a=1
  • b=-12
  • c=7

Then the line of symmetry is ...

  x = -b/(2a) = -(-12)/(2(1)) = 6

The line of symmetry is x=6.
