Work Step by Step
When looking at the equation, we can determine our a,b,c values. a=-1, b=0, and c=6. There is a negative coefficient in the equation so the graph will open downwards. To find the axis of symmetry of the equation, use the formula -b/2a and plug in your a and b values to get the answer 0. Answer choice B is the only answer with the axis of symmetry x=0 and opens downwards. Therefore, the answer is B.
