Full solution stays hidden until you ask for it.
1. Identify the vertex x-coordinate.
2. Choose one side of the vertex to make the function one-to-one.
3. State the restricted domain.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Restrictions that include both sides of the vertex for a full parabola.
