In this lesson, we will learn what a function is and why it is important in math. We will then explore common function such as linear functions, quadratic functions, cubic functions, and more. A function is a mathematical rule that assigns input numbers to output numbers. The rule is usually a calculation. So the function takes the input numbers and performs a calculation on them, then assigns these output numbers paired with the corresponding input number. These pairs of numbers can then be graphed on an xy coordinate plane, so that we can visualize the function. Linear functions have a power of x equal to 1. Quadratic functions have a power of x equal to 2. Cubic functions have a power of x equal to 3. There are also more advanced functions such as exponential and logarithmic functions we will learn in future lessons.
