[ Ax2 + Bx + C ] is one example.
Whenever you are describing an object in motion that is accelerating or decelerating (due to gravity for example), the resulting equation will be quadratic. This is just one example.
St. Louis Arch is an example of a quadratic graph. Umm... many arches are actually *catenaries*, visually indistinguishable from a parabola - this answer should be checked for accuracy.

You just have to follow the rule of quadratic functions. Example y = mx+b is the rule for linear functions. ax^2+bx+c is the rule of quadratic equation.
Many situation can be described by quadratic equations. For example, the height of an object when dropped or shot up in the air.
In problems of motion, especially involving constant acceleration, a quadratic equation will from the formulas of motion to solve for time, usually. This is just one example.
Functions are an integral part of mathematics, and most students learn them from Algebra II and up. A real life example of a function would be the relation between the height of a ball and how long it has been in the air.
Quadratic is an adjective that is used to describe something that is related to squares. For example, the quadratic equation uses squares, or the second power, and is thus quadratic.

A quadratic of the form ax2 + bx + c has no maximum if a > 0: it gets infinitely large. If a = 0 then it is not a quadratic. If a < 0 then the quadratic does have a maximum, and it is -D/4a where D is the discriminant = b2 - 4ac
x2 + 3x + 4 This is quadratic because the highest exponent of x is 2, and it is an expression because there is no equals sign.
