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.
What are the 4 steps to solving using a quadratic formula?
How to solve a quadratic equation using the Quadratic Formula.
- Write the quadratic equation in standard form, ax2 + bx + c = 0. Identify the values of a, b, c.
- Write the Quadratic Formula. Then substitute in the values of a, b, c.
- Simplify.
- Check the solutions.
How can quadratic equations apply to real life situations?
Quadratic equations are used in many real-life situations such as calculating the areas of an enclosed space, the speed of an object, the profit and loss of a product, or curving a piece of equipment for designing.
