Full solution stays hidden until you ask for it.
1. Place vertex or intercepts first.
2. Draw the axis of symmetry.
3. Add symmetric points and sketch the parabola opening in the stated direction.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Graph that violates symmetry or opening direction.
