QT Review

Quadratic functions are common in the world. The familiar shape of the parabola is easily seen in a fountain, where water arcs up in the air before it is pulled back to earth by the force of gravity. It seems like a paradox that the complexity of nature can be expressed in such mathematical simplicity, but time and again humans have observed the unreasonable effectiveness of mathematics in the natural sciences. Case in point: the equation h = t2 (where h signifies height above the ground and t signifies time) plots out, with great accuracy, the path of any object thrown vertically into the air. Understanding quadratic theory is one of the most basic and useful mathematical principles that underlies the fabric of the observable world.

So much for the philosophical spiel. 11M8, you've now finished the quadratic theory topic and completed the associated review test. Therefore I've made the quiz itself (and my scanned worked solutions) available for download. I hope this is a useful revision tool for you in the weeks and months to come!
