When we try to "model" a projectile function, which means we are trying using math to explain the shape of the path an object follows when thrown into the air. Which points on that path do you think would be critical points. Think about which points on that traveling path would matter to a baller? When it reaches the highest point? Of when it drops to the ground. Pick one sport or one situation where you would throw things up in the air then down, and talk about the critical moments that matter. Again, take risks, and share your ideas.
