Work Step by Step
When looking at the equation's coefficients, we can determine the a,b, and c values. a=1, b=6, c=0. This equation has a positive coefficient so it opens upwards. To find the axis of symmetry for this equation, use the formula -b/2a. Plug in your a and b values into this formula to get the answer -3. Since answer choice A is the only answer with the axis of symmetry x=-3 and opens upwards, A is the correct answer.
