Answer
A
Work Step by Step
$a = 1, b = 6, \space \text{and} \space c = 0.$ a is represented by a Positive coefficient, so the graph opens upward.
Use the axis of symmetry formula,$ -b/2a$ to find the axis of symmetry.
$$-(6)/2(1)\\
-6/2\\
-3$$
After solving, we find that our axis of symmetry is x = -3.
These characteristics best represent answer choice A.
