Full solution stays hidden until you ask for it.
1. Use opening direction to decide whether vertex is max or min.
2. If the domain is restricted, also check endpoints.
3. State both input and output value.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Maximum for upward-opening unrestricted quadratic.
