Question

Sergio is standing on top of a building and decided to kick a ball to his friend on top of another building. The trajectory of the ball is moving upward until it reaches a maximum height, where it proceeds to move downward until it lands on the other building. Which family of functions (linear, quadratic or exponential) would best model this situation? (1 point)
Responses

Exponential function
Exponential function

Quadratic function
Quadratic function

Linear function

Answer 1

Quadratic function

Reason: Under constant gravity the ball's vertical position vs. time follows a parabola (up, reaches a maximum, then down), which is modeled by a quadratic function.
