Full solution stays hidden until you ask for it.
1. Use -b/(2a) to find the vertex x-coordinate.
2. Evaluate for the vertex y-coordinate and y-intercept.
3. Factor or use discriminant to find x-intercepts when real.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
