#### Answer

B

#### Work Step by Step

We can define our a, b, and c values by looking at the equation's coefficients.
a=-1
b=0
c=6
There is a negative coefficient in front of the x term, so the graph will open downwards.
To find the axis of symmetry, we must use the equation: $\frac{-b}{2a}$. Plug in our given values for a and b:
$\frac{-(0)}{2(-1)}$, which simplifies to 0.
Therefore, the axis of symmetry is x=0.
These qualities that the graph has best represents answer choice B.
