The new key concept in this unit is the graph of the quadratic function. Students will learn not just how to graph these functions, but also how to predict the shape, location, and direction of a parabola from its equation. By the end of the unit, they'll also know how to solve quadratic equations by completing the square and by using the quadratic formula. Students will also have experience applying these techniques to systems of non-linear equations. This unit includes a topic on applications of quadratic functions, so the students can now start to put the procedures and formulas learned in the previous few units to good use, and solve real-world math problems that can only be tackled using these new and powerful techniques.
