Given a quadratic function in standard form, \ =\ ax^2\ +\ bx\ +\ c)
The 
-coordinate of the vertex is:
The 
-coordinate of the vertex is:
 = f\left(\frac{-b}{2a}\right))
The equation of the axis of symmetry is:
The domain of all polynomial functions regardless of degree is the set of all real numbers.
If 
then the range is \ <\ \infty)
If 
then the range is \ \leq\ y_v )
