by Taylor Miller
1. What is a Quadratic Function?
1.1. A quadratic function is where a, b, and c are numbers not equal to zero. The graph of a quadratic function is a curve called a parabola.
2. What is the rule of a Quadratic Function?
2.1. The graph of a quadratic function is a curve called a parabola.
3. Example of a Quadratic Function?
3.1. Throwing a ball.
3.1.1. You can use a quadratic function to find the amount of time it takes for the ball to hit the ground.
3.1.2. When you graph this function, it will be a parabola.
3.2. Tracking net worth.
3.2.1. You can use a quadratic function to find the amount of money you'll get after production, selling, and paying workers for your item.
3.2.2. The graph will be a parabola. It can show the height of sales, the low of sales, the lowest possible amount of profit you can get , or the most possible amount of profit you can get.
4. What is the formula of a Quadratic Function?
4.1. f(x) = ax2 + bx + c,
5. What is a Piecewise Function?
5.1. A piecewise function is a function that is a combination of one or more functions.
6. Example of a Piecewise Function.
6.1. Movie tickets.
6.1.1. Different prices for different age groups.
6.2. Selling Mixed nuts.
6.2.1. Different prices for different amounts of nuts. (usually pounds).
