Definition of Standard form of a quadratic function: The standard form of a quadratic function is when the quadratic is written as f(x) = ax2 + bx + c 12. Place each of the following functions in standard form and identify the values for a, b and c. (these are the same functions that we evaluated in Activity 1, Number 5 just in a different format)

Quadratic Equations
Standard Form of Quadratic Equations: ax2 + bx + c = 0. Before you select the method that you will use to solve a quadratic, you must use inverse operations to get the equation to equal . zero (if necessary). When solving quadratic equations, we can use two methods: Factoring.

Quadratic equation in standard form (vertex form): f(x) = a (x-h) + k. h & k are the x and y coordinates of the vertex. EX: f(x) = 1/3 (x+6) - 3 the vertex is: (-6,-3) Discriminant: b – 4ac. when: b - 4ac > 0 (there are 2 roots) b – 4ac = 0 (the 2 roots are =) b - 4ac < 0 (complex conjugates - imaginary) ...

We usually write the defining equation for a quadratic function in one of two useful forms. These are: Standard form: Vertex form: We may ask a number of questions about a given quadratic function. The means used to obtain the answers often depend on the form in which the defining equation is written.
