Full solution stays hidden until you ask for it.
1. Use vertex form directly or compute -b/(2a).
2. Identify the x-coordinate of the vertex.
3. Write the axis as a vertical line x equals that value.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Giving the vertex as an ordered pair when the prompt asks for the axis.
