Ø Write, solve, and graph problems using vertex, factored, and general form of the quadratic function. Ø Change a quadratic function from one form (factored) to another (general) and justify when and when such a change should be made. Ø Use multiple representations to model quadratic functions Ø Use the quadratic formula, factoring, and completing the square to solve equations.
