7 Quadratic Equations
LEARNING OUTCOMES
After completion of this chapter, the student should be able to:
Identify quadratic functions
Solve quadratic functions by factoring, by completing the square, by using the quadratic formula, and by graphing
Solve application problems involving quadratic equations
Graph a quadratic function and identify important points on the curve
In this chapter, we develop algebraic and graphical methods for solving an important type of equation called a quadratic equation. We will also see that the graph of a quadratic function is a parabola, which has many modern applications in science and technology.
One important application of a parabola is a television satellite dish. Because of its parabolic design, incoming ...
