Full solution stays hidden until you ask for it.
1. Find zeros and average them for the axis.
2. Evaluate the function at the axis value.
3. Write the vertex as an ordered pair.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Axis of symmetry alone when vertex is requested.
