Problem 5 of 7
Build a quadratic function for projectile context: A stone is launched from a 100-meter cliff with an initial upward velocity of 20 m/s, using a gravity term of -9.8t^2.
Using a hint is okay. It just tells the trainer to give you a little more review.

identify initial height, velocity, and gravity-style term.
Hidden until you reveal it.
Context must supply initial height, initial velocity, and gravity-style quadratic coefficient.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Use the gravity coefficient as the t^2 term.
2. Use initial velocity as the t coefficient.
3. Use initial height as the constant term.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Missing initial height or wrong sign on gravity term.
