What are three examples of quadratic functions in real life?
Throwing a ball, shooting a cannon, diving from a platform and hitting a golf ball are all examples of situations that can be modeled by quadratic functions. In many of these situations you will want to know the highest or lowest point of the parabola, which is known as the vertex.
What are the 3 methods to solving quadratic functions?
There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square. To solve a quadratic equation by factoring, Put all terms on one side of the equal sign, leaving zero on the other side.
