This document describes what a quadratic function is. I have also described how quadratic equations are solved and finally, I present some applications of quadratic functions.
In it you will find the following ideas.
I. Quadratic Functions in Standard Form
II. Solving Quadratic equations
a.) By factorization
b.) By using the principle of square roots
c.) By the completing of squares method
d.) By using the quadratic formula
e.) By graphing
III. Finally in the last section, I present some vivid applications of quadratic functions!
