As We are in sport theme lets also see another way where quadratic function is applied, as you can see under there is a bridge and what does the form if this bridge suggest you? An arc! This arc as in the other times can be represented as an expression, with the use of? QUADRATIC EQUATIONS!! WOW they are everywhere! Also in the things that we eat..

I know it may seems strange, but also the banana can be represented s a quadratic equation!

And if we want to go back in time, we can see that quadratic equations were presents also there! As when they threw the bombs with the cannons the movement was representing a quadratic equation.
