connect coefficient to opening direction and vertical stretch.
Hidden until you reveal it.
Expression must be quadratic and context must make the coefficient meaningful.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the coefficient of the squared term.
2. Use its sign to describe opening direction.
3. Use its magnitude or context to explain its effect.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying only 'it is the number before x squared'.
