Definition: A polynomial? of first degree in one variable is called a quadratic function or quadratic equation.

Definition: A polynomial? of second degree in one variable is called a quadratic function or quadratic equation.

BTW: Don't be fooled. Changing c does not change the size of the quadratic - it only moves it up and down!
