we know that
The equation in vertex form of a vertical parabola is equal to

where
(h,k) is the vertex of the parabola
and the axis of symmetry is equal to the x-coordinate of the vertex
so
-----> equation of the axis of symmetry
In this problem we have

Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation


Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares
the vertex is the point 
therefore
<u>the answer is</u>
The axis of symmetry is

see the attached figure to better understand the problem

Answer:
The median
Step-by-step explanation:
If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.
