Question

Which of these situations would best be represented using a quadratic function: the distance driven on a road trip, the path of a tennis ball hit over the net, or the path of a train on train tracks? Explain why you chose your answer.

Answer 1

Quadratics have the parabola shape.  The distance driven on a road trip and the path of a train on train tracks can be represented linearly.

The path of a tennis ball can be represented by a quadratic function.
